What glue is best for gluing. How to glue plastic to plastic tightly? Who would have thought

It would seem that solving the problem of restoring a broken plastic thing is simple - for this you need to connect its broken parts and glue it together. But the use of glue does not always give the expected result. And all due to the fact that all adhesives for plastics are different. To answer the question of how to glue the plastic tightly, you should study the features and properties of the most popular compounds, and choose the best one among them.

Types of glue for plastic

It is sometimes more difficult to glue materials made of synthetic polymers than ceramics and metals. The structure of the plastic is characterized by a smooth surface and therefore low adhesion. In industrial production, welding is used to connect plastic parts. Gluing plastic at home in this way is impossible, so the repair is carried out with glue.

The main component present in most adhesives is a special mixture that dissolves synthetic polymers. To impart viscous properties to the compositions, liquid polystyrene is added to them.

The principle of operation of such compositions is to dissolve parts of different surfaces. After squeezing them under pressure, there is a strong adhesion of the glued parts to each other.

Depending on the composition, all adhesives are divided into the following types:

1. hot melt glue;
2. contact;
3. liquid;
4. reactionary.

To figure out which glue is better to glue plastic, it is necessary to study the properties and characteristics of each type of glue.

Hot glue

Such bonding compounds are solid rods. To impart adhesion properties, they must be heated to a certain temperature. For this purpose, special pistols are used.

As a rule, hot melt adhesives are used in creative work, since they have a low bond strength and are poorly suited for precision work.

Hot melt adhesives can also be found in stores that are designed to be used without a gun. Their advantage is ease of use and fast hardening.

Contact

Those who are thinking how to glue plastic at home simply and quickly should pay attention to contact adhesives. Some of them come with a special hardener. Getting started, you need to mix the two compositions according to the instructions on the package.

Such compositions are capable of rigidly connecting plastic parts, but they are highly toxic. You need to use contact adhesive for plastic, strictly following the instructions.

Before joining two parts with contact adhesive, you should wait at least 10 minutes until it dries, and only then press the two parts tightly together.

Liquid

Liquid substances are simple and affordable, but at the same time they have the lowest quality of connection of plastic parts. They can be water-based or solvent-based.

It is recommended to use them for working with small objects that will not be subjected to stress in the future. Liquid adhesives are not prone to degradation of the plastic structure. This is very important when working with small parts, as glue that dissolves plastic can deform them. They harden for a long time, therefore, after repair work, it is necessary to leave the glued parts for at least a day.

Reactionary

Such household compounds are considered the most reliable, and at the same time they are among the most affordable. It should be noted that many of them have their own peculiarities of application.

So, when working with some of them, the parts to be connected must be left to dry in the open air. Other formulations require exposure to ultraviolet rays, while others only work underwater.

Reaction adhesives can be:

• One-component.
• Two-component.

Both one-component and two-component plastic adhesive can include components such as polyurethane, epoxy resins, polyesters.

Best waterproof adhesives

Waterproof compounds are used to join parts that are exposed to moisture. For example, PVC pipes and other plastic materials in the bathroom or kitchen are connected with such adhesives.

The best glue for plastic, according to many, is Moment Plastic. It belongs to contact and perfectly connects almost all types of plastic. Due to the presence of harmful substances in its composition, they are not recommended to glue objects in contact with food or human skin.

Moment Plastic dries up very quickly, it is cast with high strength even under the influence of moisture, temperature fluctuations, alkalis, acids.

This epoxy adhesive for plastic has a super fast adhesion - it cures within 20 minutes after application. The composition is simple and easy to use, it is good for them to seal cracks and fasten chipped parts. It is suitable for all major types of plastics.

Loctite 406 is a waterproof plastic adhesive that is easy to apply. When applied, it spreads well over the surface. Loctite 406 is characterized by its high strength properties for bonding both glossy and rough surfaces.

Best Heat Resistant Adhesives

When the question arises, how can plastic be glued to plastic in places where high temperatures are affected, you should pay attention to heat-resistant compounds. Such substances are able to withstand high temperatures for a long time without losing their initial strength.

Rexant is a clear plastic adhesive, available in pistol refills. This manufacturer also produces rods in green, blue and other colors, which are used to visually mask joints when gluing colored parts.

This heat-resistant and moisture-resistant adhesive sealant contains silicone that hardens when exposed to humid air. The adhesive is highly heat resistant and can withstand temperatures up to 300 ° C.

When using hot melt glue to bond plastic, remember that the plastic materials themselves are not able to withstand high temperatures.

Elite Drakon is a polymer adhesive for plastics, parquet, ceramics, wood and other materials. With the help of this tool, you can glue materials of different composition without fear for the quality of gluing. The dragon has high adhesion and heat resistance.

With the right choice of glue and its optimal use, any plastic part can be successfully glued. Compliance with the recommendations specified in the instructions will allow you to restore the broken thing without unnecessary material costs.

Often we need to glue a broken or cracked plastic piece - from the shackle of glasses to the bumper of a car. You may also want to glue the hook in the bathroom or the holder for the garden spray. The essence of the bonding process is to dissolve the surface layer of two blanks and form a layer of plastic from this solution, which is common to both parts. After hardening, the parts form a single whole, or, as they say, "stick together tightly."

Determine the type of plastic

in order to reliably glue the plastic, first of all, you need to find out what kind of plastic the item is made of. Knowing the plastic, you can choose the most suitable adhesive for it.

All manufacturers mark their plastic products with the symbol of recycling - this is the well-known Recycling Triangle - a triangle with arrows on the sides, symbolizing the reuse of materials.

The triangle contains numbers from one to seven. Often, the numbers are supplemented with an abbreviation. These designations determine the type of plastic.

What does marking on plastic mean?

• PET low pressure polyethylene or polyethylene terephthalate. It is mainly used for packaging or packaging food. It is produced in the form of a film, bags or transparent containers for liquid and bulk goods, as well as drinks.
• HDPE is a compacted low pressure polyethylene. Used for the release of shrink wrap and packaging bags.
• V (PVC) polyvinyl chloride is a non-food plastic used for the manufacture of strong and durable items such as household buckets, metal-plastic window frames, linoleum.
• LDPE High pressure low density polyethylene. It is used in the production of bottles for drinks and dairy products, packaging bags, toys, pipes for cold water.
• PP polypropylene. Plastic is chemically inactive, heat-resistant (up to 150 ° C), most widely used in the production of medical products, heat-resistant dishes and household utensils, toys, pipes and fittings for hot water, and much more.
• PS polystyrene. Also food grade plastic, it is used to make disposable tableware, household utensils, kitchen utensil cases. If it is foamed, it forms an excellent porous heat insulator - polystyrene used in everyday life and in construction work.
• O Other - non-recyclable materials such as those containing metal, paper or other substances). This also includes plastics that do not belong to one of the six groups.

PS - polystyrene

In order to reliably glue the plastic, you need to carefully consider the markings on the product and select an adhesive designed for polymers of this group. There is another way to determine the type of plastic - a small piece of it must be set on fire. Each type burns with a characteristic smell and type of flame. To use this method reliably at home, you need to acquire considerable experience.

Adhesive marking

Tubes with glue are also marked, it is a pity that the designation system does not always coincide with the designations in the triangle on the plastic product. Most often, the following symbols can be seen on the tube:

• PC - polycarbonate (used for covering greenhouses and sheds).
• ABS is a copolymer of acrylonitrile.
• PP polypropylene.
• PPMA organic glass for general use.
• PE is the familiar polyethylene.
• PVC is another familiar one - vinyl, or polyvinyl chloride.
• PS - polystyrene.
• PA 66 is polyamide.
• PUR polyurethane.

If you are not an expert in organic chemistry, then, most likely, further study of labeling at home will not be successful. It is better to read in the user manual, which must be attached to the tube, which plastics can be glued to them.

Types of adhesives

The variety of plastics used in everyday life corresponds to an equally wide variety of manufactured compositions and methods of their use.

How to glue plastic

To dissolve the surface layer of a material, it is necessary to break the chemical bonds between the molecules. For this, special substances are used, strong solvents. Each solvent is suitable for its own group of plastics, and it may not even leave a trace on material from another group. Each adhesive is based on such a solvent. In addition, the composition may include:

• a hardener to help dry it;
• filler - dissolved molecules of the substance for which the glue is intended.

One of the strongest solvents is dichloroethane. It is used to bond polystyrene and plexiglass.

Depending on the method of application, the funds are divided into several groups:

• liquid;
• contact;
• reactionary;
• hot melt adhesives.

Liquid

Liquids are widespread in everyday life, they are easily and simply used at home for gluing plastic with a porous structure. They are available in both organic solvent and water based. They are applied to surfaces that are pressed against each other for a time sufficient for the base to evaporate. After that, the adhesive layer hardens, forming a connecting seam. A typical example is PVA glue, which can be used to glue not only linoleum, but also wood at home.

Contact

Bonding takes place in two stages:

• the surfaces to be glued are lubricated with a thin layer, which dissolves the surface layer of the plastic, softening it and facilitating contact with another surface;
• after a few minutes, the parts are pressed against each other with force, the softened layers are mixed, the solvent evaporates and a seam is formed.

This is how Moment, BF-2 and others work. They can be used to glue polystyrene and other plastics at home. They contain toxic substances, so you need to work in a well-ventilated area and do not allow drops to get on the skin or mucous membranes.

Reactionary

One-component reactive agents dissolve the material to be bonded very quickly and harden just as quickly. These are such well-known brands as Secunda, Superglue and their analogues. The seam is strong and tough.

Two-component components consist, respectively, of two components, stored separately from each other:

• hardener;
• fixer.

The components are mixed immediately before use and applied to surfaces where the mixture hardens to form a compound. The base is epoxy or polyester resins. The seam at home is very durable. A characteristic feature is that complete hardening takes a long time, and the seam gradually increases both strength and fragility.

Hot melt adhesives

This group includes substances that show their properties when heated to 110-120 ° C. For use, a special glue gun with a heating element is required. Differs in the accuracy of application. In addition to plastic, they can glue wood, fabric, paper at home.

How to glue plastic tightly at home

After the type of plastic has been determined and the appropriate substance has been selected, you should:

• thoroughly degrease the surfaces to be glued. To do this, use alcohol, degreaser or soap solution (only laundry soap);
• to glue objects more reliably, you need to increase the wettability. To do this, treat the surfaces with a velvet file or a thin sandpaper;
• mix two-component reactive substances only after the preparation of the parts;
• do not use brushes with natural bristles;
• Apply so much adhesive that when pressing the blanks, the excess is not squeezed out of the bonding zone.

The parts should be pressed so as to exclude their displacement in the plane of gluing relative to each other.

How to achieve maximum effect when gluing plastic parts

For gluing plastic at home to give the maximum effect, you should:

• accurately determine the material and select the appropriate adhesive for it;
• carefully follow the requirements of the instructions for use;
• wait for the allotted time for the strength of the seam and do not try to use the product ahead of time;
• for outdoor use or for items used in high humidity conditions, you need to choose a waterproof grade;
• despite the declared heat resistance of the adhesive, the parts themselves may not survive this temperature;
• if there is no marking on the product, then you can try to drop a drop of adhesive in an inconspicuous place and see if the material dissolves.

Epoxy adhesive provides one of the strongest bonds and is compatible with many types of plastics.

What affects the reliability of gluing

A number of conditions affect the reliability of the seam. All of them are important, and non-observance of any one can lead to the fact that the glued at home will fall off, despite the observance of all the others. So:

1. Compliance of product material and adhesive.
2. Correspondence of the type of adhesive to the magnitude of the forces that the connection will experience. The direction of action of these efforts is no less important. So, compounds that give rigid seams are not suitable for repairs, for example, shoes - after all, the sole during operation will bend and twist, despite the fact that the tensile force will be small. At the same time, with this composition, you can successfully glue, say, a hook to the glass, and hang tens of kilograms on it.
3. Compliance with application technology. Everything is important here - and how many seconds or minutes the surfaces need to be squeezed, and how to degrease them, and how much to keep the parts pressed against each other. All this depends on the properties of a particular pair of "plastic-glue", is described in detail in the instructions and must be followed verbatim. A second deviation in the holding time or premature use of the product may result in secondary damage.
4. The mechanical part of the process. It is important to thoroughly remove dust from the surface and roughen it. In addition, the direction of pressing the parts against each other should be perpendicular to the surfaces to be glued. It is impossible to allow mutual displacement of parts after pressing - this will also lead to failure.

Gluing plastic tightly is not so easy. Careful adherence to a home craftsman simple rules will allow you to get strong and durable connections. The main thing is not to forget about safety precautions: do not inhale the vapors of the adhesive and do not allow it to get into food, on the skin or mucous membranes. If accidentally swallowed, you should immediately consult a doctor, be sure to take a tube with you.

Basically, to solve the problem of broken plastic things, they start gluing them together. Although success is not always achieved, as it is a rather complicated process due to the nature of certain types of adhesives and plastics. This article will talk about glue for plastic, how to choose and use it, and also find out the answers to various popular questions, for example: how to glue plastic to plastic.

Features and purpose of glue for plastic

Plastics are known to belong to the group of materials that do not adhere well. For example, ceramics are much simpler when compared to ordinary plastic. This can be explained by the surface structure, chemical composition and properties of plastics, namely the absence or small pore sizes, low chemical activity of polymers, low adhesion and other properties of plastics. In this regard, in construction, industry and other areas, welding of plastics is more reliable than gluing.

Although it is not available at home, other methods of mechanical connection of plastic parts are not always applicable. In this regard, special types of adhesives are mainly used for the repair of plastic structures. Thanks to special types of glue, it is sometimes possible to restore a broken plastic part, worn out shoes, a toy or other things necessary in everyday life.

Plastic glue is a useful and convenient thing, but the gluing process can cause many problems in some situations. The fact is that different types of plastic differ in different properties, and each glue is characterized by certain application features. We will begin our acquaintance with the nuances of gluing plastic by considering the types of glue that exist today, their features, advantages and disadvantages.

How to glue plastic to plastic tightly

Today on the market you can find many brands of glue, different in composition, method of use, and also the principle of action.

Adhesives for plastics can be divided into 4 categories:

1. hot melt glue;
2. reaction adhesive;
3. contact adhesive;
4. liquid glue.

Each type of glue has its own areas of application and characteristics. Next, each of the types will be considered separately in more detail.

Liquid glue

This type of glue is the easiest to use and composition, therefore it is considered very popular among users.

There are the following types of liquid adhesives:

• solvent adhesives;
• water-based adhesives.

If we consider water-based adhesives, then they differ significantly from their counterparts, although their principle of operation is the same. During the application of liquid glue on the surface, the solvent or water begins to gradually evaporate, then the glue hardens and the elements are glued directly.

They are well suited for gluing, for example, porous materials through which water or solvent evaporates. It should be borne in mind that it is very difficult to glue sealed materials with them, or it is generally impossible, because even after a long time, such glue remains liquid.

Such a well-known to everyone as referred to as liquid, it is traditionally used for gluing fabrics, paper, wood, as well as for gluing plastic films on furniture and similar materials. Liquid adhesives also include resin and rubber adhesives that use methyl acetate, acetone, alcohol, etc. as a solvent.

Adhesives based on dichloroethane have been used for a very long time, but due to their toxicity, they are used only by professionals at enterprises, which is explained by their harmfulness. Next, we will consider in more detail how to glue plastic to plastic, namely what types of glue can be used for this.

Contact adhesives

This type of glue is mainly used for gluing different types of plastic, because it is very easy to use and gives good results.

There are several types of contact adhesives:

• with a hardener;
• without hardener.

Regardless of the type, the use of contact glue can be described as follows: at the very beginning of the gluing process, the glue is applied to one or both surfaces to be glued, then it must dry for 10-15 minutes. After that, the surfaces to be glued must be pressed tightly together. Because of this, such adhesives are called contact adhesives, since they, after drying and contact, connect the materials that are glued.

Contact adhesives include the following: "Moment", BF-4, BF-2, rubber glue and other brands. This type of adhesives often contains toxic materials, in this regard, it is necessary to work with them strictly according to the instructions, namely in a ventilated room, while avoiding skin contact with the adhesive and inhaling vapors.

Reaction adhesives

Such adhesives are classified into 2 types:

• two-component;
• one-component.

One-component adhesives contain a special hardener that remains liquid in a closed container. When applied to the glued surface, it instantly hardens, while connecting the necessary parts. These include the well-known cyanoacrylate "Second" adhesives "" and its analogs. Their hardening is carried out under the influence of water vapor and oxygen contained in the air. In this regard, during their use, experts advise to moisten the surfaces, while most other adhesives, on the contrary, adhere well to dry surfaces.

Two-component adhesives, respectively, consist of 2 components: a hardener and a binder. Before gluing, they are in different containers. Before use, such adhesives must be mixed, then they are applied to the surfaces to be glued, and the mixture itself begins to harden under the influence of certain environmental factors. After mixing, the two-component adhesive can be stored for no more than half an hour.

Basically, they are based on various resins, the most famous adhesives of this type include polyurethane, epoxy, polyester and others. There are also two-component PVC-based adhesives, although they are usually only used in industry.

This group of adhesives is considered special, since they acquire adhesive properties only when heated to a certain temperature (depending on the glue, it will be 110-220 ° C).

Hot melt glue can only be used with a special glue gun, thanks to which the glue will heat up. In most cases, they are used for creativity, with their help, you can glue, for example, large parts, but it is not always possible to glue broken plastic things.

Let's note the fact that now manufacturers from different countries have created a large number of adhesives for gluing plastic, while many of them are suitable exclusively for industrial use.

This is due to the following factors:

• toxicity of some brands of glue;
• the complexity of their use, because some brands of glue can work in conjunction with catalysts and only if the conditions prescribed by specialists are observed;
• their high cost, etc.

For household use on the market, you can find not so many brands of glue, including such popular brands as BF-4, BF-2, Moment, rubber glue, second adhesives, one-component liquid adhesives and a number of 2-component resin-based adhesives ... Basically, you have to choose from a limited supply, on the basis of this, the right choice of glue is the key to a good repair of a broken thing.

How to choose an adhesive for plastic?

Basically, for gluing plastics, they use universal adhesives, which include the popular "Moment", various brands of second-hand adhesives, epoxy, etc. But there are also various special adhesives designed for gluing one or several types of plastic.

Such adhesives are designated by an abbreviation, which indicates for gluing which type of plastic they are intended for.

Let's consider which abbreviations are the most popular:

1. PA66 - polyamide;
2. ABS - plastic, acrylonitrile butadiene styrene;
3. PP - polypropylene;
4. PE - polyethylene;
5. PS - polystyrene;
6. PC - polycarbonate;
7. PUR - polyurethane;
8. PMMA - polymethyl methacrylate;
9. PVC - PVC, polyvinyl chloride.

There are many more types of plastics than indicated above, so other abbreviations can be found. On the packaging, the plastic designation can be found in the corners or under the recycling (reusable) plastic sign.

For gluing plastics that are found in everyday life or in cars, these second adhesives, epoxy adhesives, contact adhesives, for example, "Moment" and others, are also suitable. In this case, you need to choose glue, not only based on the material, but also on the basis of the features of the use of the glued object:

Reactive and liquid adhesives work best in fixed joints, the task of which is to provide high bond strength. Many reactive adhesives are excellent at bonding various parts that are exposed to constant heat.

From a different perspective, though, a large number of adhesives cannot be used with certain types of plastics. This is especially true for solvent-based adhesives, as they can damage the surface of the plastic. Therefore, these types of adhesives must be used with great care.

Separately, I would like to highlight the bonding of such well-known plastics around people as polyethylene. Most adhesives cannot bond these types of plastics. For example, try to glue a regular plastic bag using Superglue and Moment, and you will see that nothing comes of it. A glued polyethylene part will usually fall apart soon, so you don't even have to think about repairing such a part with glue, so there is no point in trying either.

Instructions for the use of adhesives for plastic

Special instructions on how to use the glue should be on its packaging. Let's look at a procedure that would be typical for working with a variety of adhesives.

Liquid adhesives

In most cases, this type of glue should be applied to one of the surfaces that is glued. After that, the two surfaces need to be connected and squeezed until the glue dries completely. In some cases, experts first advise applying the glue to two surfaces, and then letting it dry. Next, you will need to reapply the glue to one of the surfaces, connect and squeeze both parts until the glue is completely dry.

If, for example, we consider liquid adhesives, then their advantage is that they do not dry quickly. In this regard, the position of the parts that are glued together will be able to slightly correct relative to each other after they are connected.

Reactive one-component adhesives

Basically, adhesives of this type are applied in a small layer on surfaces, which must be immediately pressed against each other. The glue should harden for a few seconds, which is why they are called seconds, based on what was written above, you cannot hesitate when gluing.

When bonding with cyanoacrylate glue, the professionals advise breathing on the surfaces to be bonded for better adhesion. Thanks to water vapor, the reaction will go much better. For some types of one-component adhesives, it is advised to wet the surfaces slightly so that they become slightly damp.

To work with this type of glue, you first need to mix its components (basically this should be done in a one-to-one ratio, although there are other options). After that, gluing is carried out in the usual way - glue is applied to both surfaces, after which it is compressed until it is completely dry.

Basically, the glue in a mixed state can "live" no more than half an hour, which is why it must be diluted in such an amount that will be used in full within the time specified in the instructions for use.

These types of adhesives are formed into rods of different diameters, intended for use with a special glue gun. With this type of glue, the work is quite simple - first you need to insert the bar into the gun, then you need to turn on the gun and then wait for the glue to heat up. To glue the surfaces, you first need to squeeze a drop of glue onto the part, and it, in turn, adheres to the base to be glued.

As for the hot melt glue outside the gun, it dries very quickly (practically in a matter of seconds), so with its help the parts need to be glued very quickly without any mistakes. A selection

Colorpolychloroprene adhesives - yellowish brown.

By Areas of use Polychloroprene adhesives are divided into two groups:

2.1. for rigid gluing(hard glue line);

2.2. for flexible gluing(flexible, elastic glue seam).

2.1. Polychloroprene (neoprene) adhesives for hard glue line - these are adhesives with relatively short molecular chains, the glue line of these adhesives is quite tough and durable. Adhesives have good adhesion to metals, glass, wood, stone.

They are mainly used for fastening to hard surfaces, to metal (including painted), wood, concrete, brick, plastered surfaces) of materials such as rubber, textiles, carpet, linoleum, decorative elements, plinths, platbands.

To improve the adhesion strength, the glue seam can be thermally activated (heated).

Polychloroprene adhesives that you can buy on our website are "Boat", "Moment Classic universal", "88", "88+", "88 Moment extra strong", "Stealth", "Auto Niva", "317", Neoprene, Super Cement, Super Monolith.

Glue "88"- one of the most famous adhesives of this group, was developed back in Soviet times by the Institute of Aviation Materials. "88" glue is waterproof. Water resistance is achieved due to the fact that the composition includes a synthetic resin.

It is used for gluing such materials: metal, rubber, wood, veneer, stone, parquet, tile, mosaic, ceramics, glass. For fixing various types of coatings (including flexible ones) to almost any surface. They are used for cladding of interiors of cars, buses, wagons, for the manufacture of seats. Very good for gluing synthetic upholstery materials to metal.

On our website you can buy several types of "88" glue from different manufacturers. By their properties, they are almost the same:

"88 The moment is extra strong" 30g, "88+" 40g and 100g,

"88" 40g and 100g, "88" (green tube) 40g.

Glue "A boat" is one of the most widely used universal neoprene adhesives and has been developed and intended for repair rubber boats, rubber products (car and bicycle cameras, raincoats, tents made of rubberized fabric, etc.), as well as for gluing leather, plastic, wood, veneer, polymer-synthetic materials (except for polyethylene), glass, porcelain.

When more and more boats made of PVC fabric began to appear, there were requests to improve the “Boat” glue formula, because the strength of the glue seam decreased due to solar heating. Then the PVC boat polyurethane adhesive was developed for boats and other products made of PVC fabric.

"Moment Classic universal"manufactured by Henkel- one of the most famous and popular polychloroprene adhesives. It is used for gluing in various combinations: wood, metal, leather, rubber, felt, fabrics, plastics, glass, ceramics. You can buy "Moment Classic" in packs of 30 g, 50 g and 100 g.

2.2. Polychloroprene (neoprene) adhesives for flexible, elastic adhesive seam with long molecular chains specially designed for footwear ( "Nairit", "Nairit shoe", "Shoemaker", "Leather").

"Nairit" - This is a special kind of neoprene rubber with long molecular chains, specially developed back in Soviet times in Armenia *. This brand of rubber was named "Nairit". Now "nairite" is called all adhesives made on the basis of nairite rubber, i.e. rubber with long molecular chains. When these molecules are joined together, the seam retains flexibility, which is very good for making and repairing shoes. If you take glue "88" - it has a very hard glue line. And at "Nairit" the seam is soft, elastic, flexible, it does not break under loads, vibrations, keeps gluing. For shoes - perfect! On our website you can buy a variety of Nairit glue - "Nairit shoe".

* "Nairit" plant Is one of the oldest chemical enterprises in Armenia. "Nairit" as a synthetic rubber plant "Glavkauchuk" named after CM. Kirov, was founded in 1936. The enterprise produced the chemical composition demanded by the national economy - calcium carbide. Since 1940, the plant has become a monopoly producer of chloroprene rubber. Until the end of the 1980s, the plant occupied 10-12% of the world market for synthetic rubber.

"Moment Shoe Marathon" – designed for gluing shoes and shoe materials made of rubber, thermoplastic elastomer, leather, imitation leather, fabric, felt, cork, plastic in various combinations.

"Shoemaker" – special shoe glue based on nairite rubber. Designed for joining the upper parts of shoes made of natural and synthetic leather with rubber and leather soles, as well as for joining shoe elements made of artificial leather, plastic leather, textile materials. It is also used when gluing coverings, lining, gluing insoles, reinforcing elements of shoes.

"Leather" - glue of increased elasticity and heat resistance for highly absorbent materials. For the manufacture and repair of products made of natural and artificial leather, shoe uppers, fabrics, felt, synthetic materials, for attaching unformed soles to the upper of shoes.

Glue "Professional" Shoes-Leather-Rubber It is used for repairing shoe uppers, products made of natural and artificial leather, rubber, fabrics, as well as repairing inflatable boats made of rubberized fabric.

Glue "Sprinter" is a universal quick-setting elastic glue for repairing footwear, including soles, leather, suede, nubuck, fur, polyurethane, PVC, rubber, fabrics. It can be used for bonding in any combination of rubber, leather, fabrics, wood, metal, glass, tiles, ceramics and porcelain.

3. Rubber glue is a solution of synthetic rubber in gasoline. Previously, for the manufacture of this glue, only natural natural rubber was used, extracted from the sap of the South American hevea tree, but now its synthetic counterparts are used.

Rubber adhesives that you can buy on our website - "Rubber" and "Latka"- used for gluing products that are not under heavy load.

"Rubber" glueis an inexpensive adhesive for non-critical connections. It is used for gluing rubber products that are not under heavy stress. "Rubber" glue is very popular with tanners: details of leather jackets and other products, before stitching, are first baited on rubber glue, and then they are stitched. It is elastic and can be easily torn. Remains of glue are removed from the material simply with gasoline.

Glue "Latka" for bicycle patches it is used to "bait" patches, which then still need to be vulcanized.

Also, rubber adhesives are used for gluing cardboard, paper, photographs.

Gluing method these three groups have almost the same. Before bonding, almost any surface to be bonded must be sanded and degreased. First, you need to apply the glue, wait until the solvent evaporates so that only the rubber layer remains, and then press the glued surfaces and hold them under load for some time.

Mode of application:

Apply an even layer of glue to the cleaned and degreased surface, dry until the stickiness disappears completely.

For responsible gluing, it is recommended to apply a second layer of glue after 10-15 minutes. after the first, also dry. The strength of the connection will increase by 1.5-2 times if the 2nd layer is heated to t ° = 50-60 ° C.

Press firmly for 30 seconds. Strength is critical, not duration of pressure. The product can be used after 1 hour. The final strength is reached after 24 hours.

For polychloroprene adhesives, it is recommended to press down as hard as possible on the parts to be bonded. This is due to the fact that these adhesives are based on short molecules, and the stronger the mechanical effect on the glued surface, the better these molecules adhere to each other, i.e. better adhesion. There is also a recommendation - to warm up the seam, or heat it up. This is also done to improve the adhesion of the bonded surfaces.

The composition of adhesivesthat you can buy on our website, no substances harmful to the body are included, called precursors, which is confirmed by the certificates of the adhesive manufacturers. At the request of wholesale buyers, we enclose a photocopy of these certificates in the product packaging.

4. Adhesives based on cyanoacrylate, or "super-glues"

Cyanoacrylate is an organic substance, the molecules of which have the ability to very quickly combine with each other (polymerize). Super adhesives, or cyanoacrylate adhesives, cure in 1–2 minutes and provide a very strong bond.

Cyanoacrylate polymerizes when exposed to moisture in the air. Therefore, if you want the glue to harden faster, and the air is very dry, it is recommended to breathe in the place of gluing.

Also, glue based on cyanoacrylate accelerates polymerization under the influence of pressure. If, for example, you drop cyanoacrylate glue on any surface, the drop will remain liquid for a long time.

General instructions for use cyanoacrylate adhesives:

1. The surfaces to be glued must be dry and clean. If necessary, clean from paint, dust, degrease.

2. Apply glue to one of the surfaces to be bonded.

3. Press the surfaces tightly and hold for 1–2 minutes.

Colorcyanoacrylate adhesives - transparent.

Super adhesives are suitable for bonding a wide variety of materials: metals, ceramics, porcelain, glass, precious stones, rubber, rubber, most plastics, elastomers, cardboard, paper, porous materials, PVC. Used for gluing any wood materials. Suitable for MDF, chipboard, wood, plywood. They are used in the manufacture and repair of furniture.

By consistency super adhesives that you find on our website can be divided into 2 groups:

Ordinary, liquid cyanoacrylate adhesives

"Super Moment", "Akfix 702", "Elephant",

"505", "Cyanopan E", "Cyanopan ME",

"Alteco 110", "Fixator 505"

· Super adhesives - " gel", "Slow", thick cyanoacrylate adhesives. They do not spread, do not absorb as quickly as conventional super adhesives, they are convenient to use on vertical, uneven, porous surfaces.

"Akfix 705", "Akfix 705 with activator",

"Super Moment Gel", "Alteco Gel", "Fixer Gel"

When working with such adhesives, special precautionary measures:

1. If in the process of working with glue your fingers accidentally stick together - do not try to break them! Carefully and slowly separate them with a round object (such as a pen). After a while, the sebum will itself reject the remnants of the glue.

2. If glue gets into your eyes, you should urgently rinse them with plenty of water and consult a doctor. If glue gets inside, make sure the airway is clear. Cyanoacrylate polymerizes (hardens) instantly in the mouth, making it virtually impossible to swallow. The saliva will gradually separate all the solid product.

4. Keep the adhesive out of the reach of children!

5. Epoxy adhesives

On our website you can find two-component epoxy adhesives that create a super-strong, hard surface that, after curing, does not shrink or deform. After hardening, it can be drilled, sharpened. The adhesives are waterproof, non-flammable.

Metal, plastic, rubber, wood, ceramics, glass, crystals, stones and jewelry (bijouterie) are glued together.

Two-component epoxy glue "Alteko 5 min" transparent for glass, ceramics, porcelain, crystal, crystals, jewelry, bijouterie.

Epoxy glue two-component "Alteco 4 min" black for metal, plastic, rubber, wood, stone, ceramics, glass.

There are other types of epoxy glue :

· in bottles in sets with a hardener: "Khimkontakt-Epoxy" 200 g, 100 g, 70 g.

· in iron cans 900 g and 3 kg with or without PEPA hardener.

· epoxy adhesive for universal use and for steel in syringes for easy mixing,

· cold welding (they are all made on the basis of epoxy resin)

In addition to all of the above adhesives, there are also other types of adhesives available:

Canned adhesives

· PVA glue

· Glue "Dragon" universal polymer

Adhesive for patches

Wallpaper glue

Often in everyday life or in the manufacture of furniture, we have to glue various materials. In the carpentry and furniture business, the skills of the master in this type of work play an important role.

The quality of the bonding depends primarily on the pre-treatment of the bonded surfaces. The surfaces to be glued are thoroughly cleaned of dirt, grease, remnants of old glue or paint; the surface must be absolutely dry and clean. Materials with a mirror-smooth surface do not adhere well to each other, so clean them with a knife, sandpaper or file.

When gluing metal, porcelain, glass stone and some other parts, it is necessary to first degrease by washing them with warm soapy water and then rinsing. You can also degrease the surface by wiping them with a swab dipped in a solution of ammonia gasoline, acetone, a solution of baking soda.

When gluing various materials, you need to follow several rules: apply the glue to the surface only with a thin layer, but so that there are no missing spots. The glue should be free of any impurities (sawdust, dust, etc.) and a uniform consistency, that is, it should not contain lumps. A thick layer of thick glue does not in the least contribute to a stronger adhesion. Some types of adhesives, according to the instructions, should be warmed up before use. We would advise you not only to heat up the glue itself, but also to heat up the materials to be glued. Then the adhesion strength will increase.

As a rule, the parts to be glued are dried in a heat of at least 18 ° C. The parts should be pressed tightly against each other using a press, oppression or vice.

When gluing wood, it is recommended to preheat the surfaces to be glued. It is desirable that the moisture content of the parts to be glued is the same, but, in any case, does not exceed 10-12%. We would recommend you to glue dry wood with animals and synthetic adhesives. Animal glues include bone and casein glues. We note right away that preparing bone glue for work takes quite a lot of time, but this disadvantage is more than offset by its advantages. It is beneficial to use when a large amount of work is being done. The joints glued with this glue are very strong, which favorably distinguishes it from others, even expensive ones, such as BF-2. The glued parts can withstand a load of up to 60 kg per 1 sq. cm, which is several times higher than that of other adhesives. And finally, the tiles of dry wood glue can be stored indefinitely, they practically do not deteriorate.

The wood glue should be prepared in a special glue machine. The glue machine consists of two tin containers, one of which (wider) is filled with water, and in the second (smaller) glue is poured and placed in the first. The glue boiler can be successfully replaced with ordinary cans, one of which is larger than the other. Such a device (water bath) prevents the glue from burning and can keep it warm for a long time. To weld bone glue, first break the dry glue into small pieces and fill with water. Let the glue swell for 10-12 hours, and then cook. To prepare liquid glue for 4 parts by weight of dry glue, take 3-4 parts of water. The glue should be warmed up, stirring, so that the whole mass is obtained without clots and grains. Do not bring the adhesive to a boil, as this may reduce its stickiness and durability. Determine the readiness of the glue by dipping a stick into it.

The glue is ready if it flows from the stick slowly, in a thick, even stream. If the glue is too thick during cooking, you can dilute it with hot water. When working, use hot glue, if it has cooled down a little, it can be heated in a water bath. Do not brew a large amount of glue right away. Brew as much as you need to carry out the work; reheating the already cured glue deteriorates its properties. When preparing bone glue, you can also make it fireproof. To do this, dissolve 100 g of glue in 200 g of water and cook it in a glue boiler until a thick composition is obtained, and then add 40 g of drying oil to it and boil it again. An increase in the stickiness of the composition can be achieved by adding zinc or lead white to the glue at the rate of 25: 2.

When preparing casein glue, take 300-400 g of room temperature water and pour 100 g of glue powder into it. The glue powder should be poured into water gradually, stirring constantly until a homogeneous creamy mass is formed. The finished mixture will be thick at first, and it is set aside for a while to liquefy. There is no need to add water to the mixture. The finished glue should drain from the stick in a continuous stream, leaving a thin, shiny film on it. Remember that casein glue is not heated, since at temperatures above 40 ° C casein curls up and loses its adhesive properties. You can prepare glue powder at home, provided the necessary components. The glue contains 7 parts by weight of dry casein in powder and 1 part by weight of borax (sodium boric acid).

To prepare glue from this powder, you need 8 parts by weight of water. Pour casein with cold water in a 1: 1 ratio and stand for 3 hours. Dissolve the borax in hot water and fill the swollen casein with the resulting solution. Stir continuously until you get a fairly thick, homogeneous mass. Parts glued with casein glue are kept under the press for 4 hours, but the glue finally dries up only after 12 hours. The big advantage of casein glue is that it can glue wood with high moisture content. Wood can also be glued with other adhesives, such as synthetic wood glue, various resin adhesives and some other uses, carefully read the proposed instructions.

Sometimes it is necessary to stick plastic, leather, leatherette, decorative plywood, fabric or synthetic film on a wooden surface. Plywood can be firmly glued to wood with casein or synthetic wood glue. Plywood and tile glue can also be glued, but this will create a noticeable dark seam. Do not apply a layer of glue directly to thin plywood as it may shrink. It is better to cover the surface of the wood with a layer of glue, and then put a plywood sheet on it and press firmly on top with pressure. The pressure should be about 8 kg, it should lie under pressure for about 7-8 hours.

To glue the plastic, use rubber-based adhesives. These can be adhesives such as 88N, Zh-3, KR-1, "Elastosila-2". Before gluing, it is necessary to carefully treat the surface of the wood or plastic.

Clean the wood from dust, and sand the back of the plastic with sandpaper until the plastic becomes a little rough. Work the corners and edges especially carefully. Then wipe the treated plastic surface with a swab dipped in gasoline to degrease it. Apply a thin layer of glue to both surfaces to be glued and connect them. Firmly pressing the plastic to the wood, run your hands from the middle to the edges to squeeze out all the air from under the plastic, and then put something heavy on the plastic so that the oppression is evenly distributed over the entire surface to be glued to be at least 4-5 kg ​​per 1 sq. ... see Oppression leave for half an hour. Such glues are finally hardened within 24 hours.

For gluing fabric, leather, leatherette to a wooden base, use adhesives: "Dubok", "Unicum", BF-6, "Polyvinyl acetate".

Also at home, if you have the necessary components, you can prepare a high-quality adhesive composition. To do this, you need 400 g of wheat flour, 30 g of rosin, 15 g of aluminum alum and 100 g of water. Mix dry ingredients, fill with water and put on low heat, or even better, use a glue boiler. In the process of preparing the glue, do not forget to stir it periodically so that no lumps form. As soon as the glue starts to thicken, it is ready. Make sure that the adhesive is homogeneous. This glue is used only hot. For leathers and leatherette (without fabric base), degrease synthetic films with gasoline with acetone. Fabrics do not need pretreatment before gluing. Cover both surfaces with glue with yourself and iron with a warm iron through a wet cloth until it dries.

It is better not to glue fabrics and synthetic films with BF-6 and "Polyvinyl acetate" adhesives, since BF-6 glue can shine through the front surface and stain fabrics in a yellowish color. The glue "Polyvinyl acetate" is destroyed by the action of water.

It is best to glue metal parts to wood using rubber adhesives, such as Zh-3, KR-1, 88-N, 88-NP, Patex, Elastosila-2. If you need to glue small metal objects (hooks, shelves) to a wooden surface, we would not recommend using the first three brands of adhesives mentioned. These adhesives form so-called "creeping seams", that is, under the action of stress, the metal object will slide off the wooden surface. Before gluing, file the metal surface to make it rough, and then degrease with gasoline or acetone. Apply a thin layer of adhesive to both surfaces to be glued, clamp the parts in a vise and leave it there for a few minutes. Finally, the glue will dry in 10-12 hours.

For gluing smooth surfaces, use the same glue "Elastosila-2".

Apply a thin layer of glue to surfaces previously degreased with acetone and leave for one hour. After that, wipe the surfaces with a swab dipped in acetone and connect them. Clamp the glued parts in a vice for 4-5 hours. Finally, the glue will harden in 10-12 hours.

Glass is most often glued with such adhesives as "Polyvinyl acetate", "Mars", "Supercement", BF-2, "Patex", "Unicum". These adhesives form practically colorless seams and are not destroyed by moisture. Before gluing, degrease the glass with acetone, apply a thin layer of glue to the surfaces to be glued and let it dry slightly for 10 minutes. Apply a second coat and after 2-3 minutes join the parts to be bonded. The parts must be tightly pressed against each other for 20-30 minutes. The glue completely hardens only after a day.

To glue glass and metal together, take "Glue-sealant", "Elastosila-2", "Unicum". Degrease both surfaces, grease with glue and clamp the parts in a clamp for 30 minutes. The glue will finally harden and become water-resistant after three days.

You can glue glass to wood, as well as stick fabric or cardboard on it with PVA, PVA-A, "Polyvinyl acetate" adhesives. Degrease the glass with acetone, grease the surfaces with glue and put the parts under the press for an hour. The glue will dry in a day.

At home, BF-2 or "Epoxy" glue is used for gluing metals. Clean surfaces from dust, dirt, rust, sandpaper. Rinse treated surfaces with clean water and dry well. Degrease surfaces with petrol or acetone. Apply a thin layer of glue to the surface and let sit for an hour. Then place the workpieces greased with glue in the oven, heated to 50-60 ° C, and dry for 10-15 minutes. Apply a second layer of glue to the metal and, as soon as it starts to dry out (stops sticking to your fingers), connect the parts to each other. It is better if you clamp the parts in a vice and dry them in the oven at 130-150 ° C for 1-2 hours. With cold drying
fully hardens only after 2-3 days.

Epoxy glue is indispensable in some cases. It consists of two components resin and hardener.

When using it, work with gloves, as the hardener is poisonous; if the hardener gets on your hands, remove it with a swab soaked in acetone, and then rinse your hands with running water. Before mixing the resin and hardener, it is advisable to warm the resin in a bowl with hot water, but not higher than 30 ° C. Mix warm resin with a hardener in the ratio indicated in the instructions, and use the prepared glue as well as others.
