What kind of glue to glue cardboard to cardboard and other materials. How to glue plastic to plastic tightly? Who would have thought Which glue is better for plastic and paper

When modeling and making various crafts, it is often necessary to quickly and reliably glue cardboard parts or glue cardboard to other materials - fabric, wood, foam, cork, metal, etc.

Unlike thin paper, cardboard is a tougher and denser material, so ordinary clerical (silicate) glue is not capable of such a task, especially when it comes to gluing large parts.

• PVA is a classic adhesive based on an aqueous dispersion of polyvinyl acetate. This composition is successfully used for gluing various porous materials - paper, cardboard, wood, fiberboard, MDF, fabric, etc. Today PVA remains the most popular glue in cardboard modeling.

Suitable for bonding almost all natural materials.

On sale you can find several varieties of this glue: stationery, household, universal and construction.

By choosing PVA glue for cardboard, we recommend paying attention to the universal PVA glue, the so-called PVA-MB. It is not as liquid as stationery, and not as rough as construction, which is used for gluing linoleum and carpet.

It is most profitable to buy universal PVA glue in hardware stores, where it is sold, as a rule, in large packages (500 g, 1 kg, etc.). As for the shortcomings, there is only one PVA glue - after drying, the parts to be glued jar a little.

• Moment Joiner Express- modern adhesive from Henkel. Designed specifically for working with wood, plywood, veneer, fiberboard, MDF, cardboard and other natural materials.

Its composition resembles PVA glue, however, it is improved with special additives that improve the adhesion of the composition, make it more elastic when it dries. Glue corrugated cardboard this glue is very convenient, since the glue seam quickly sets, eliminating the slipping of the parts to be glued.

Moment Joiner Express after drying becomes colorless, which is important when modeling - the glue will not be noticeable in the seams between the parts to be glued.

• UHU Holzleim Express Modeling Adhesive- quick-setting glue for wood, has a surprisingly high adhesive power.

Specially developed by UHU specialists for modeling, doing housework, repairing wooden furniture, etc. Designed for gluing any wood and wood-like materials in any combination.

Ideal for gluing cardboard and paper, also for gluing cardboard to cardboard.

Indispensable when fast setting of glued surfaces is required. After drying, it becomes transparent, resistant to moisture.

• Moment Universal Gel- modern waterproof and frost-resistant express glue in the form of a gel, thanks to which it does not spread or drip.

Retains elasticity after drying, does not warp or deform the parts to be glued.

Moment Universal Gel is widely used in modeling and creative work when it is necessary to quickly and reliably glue wood, ceramics, PVC, rubber, cork, fabrics and other materials.

Ideal for gluing paper, cardboard and corrugated board, incl. inclined surfaces and surfaces of a large area.

• "505" Universal second glue- a liquid transparent adhesive, similar in consistency to water. Designed for bonding metal, rubber, leather, ceramics, paper, cardboard, wood, plastic, etc.

Indispensable when you need instant fixation of small parts made of paper and cardboard during modeling.

Paper (cardboard) modeling is one of the most accessible types of technical creativity, however, when working with cardboard and glue, certain nuances should be taken into account.

In particular, it is necessary to work extremely carefully with water-based adhesives, since when the water dries, the material "pulls" and the product begins to deform.

To prevent the paper from warping during drying, the glue should be applied in a thin, even layer to one of the surfaces to be glued. After that, the parts are connected and ironed so that no air bubbles form under them.

There is no need to try to assemble the model quickly, this should be done in stages, only after the frame has completely dried.

When working with Moment glue, precautions should be taken, since it is made on the basis of solvents. It is not recommended to inhale its vapors, as they are toxic; after bonding, the product should be left to dry in a ventilated room.

In everyday life, many faced such a problem as broken plastic products. These items rarely lend themselves to any kind of DIY repair, it is safer to glue them. You can decide how to glue the plastic tightly by considering the best adhesives for various types and gluing technology.

Determine the type of plastic

Before gluing the plastic, it is important first of all to determine the type of material of the broken item. It is important to do this in order to better glue the plastic and not damage the product - many adhesives are solvents for plastic parts.

Most often, a manufacturer marks its products with a recycling symbol, which can be used to determine the type of plastic. It is a triangle with drawn arrows on the edges, inside there are numbers from 1 to 7.

Another designation of the brand is the alphabetic characters inside or next to the triangle. Knowing these designations, you can determine the type of plastic, after which the adhesive for plastic is suitable for it.

Marking

1 or PET is polyethylene terephthalate. The main area of ​​application is food packaging. It is used in the manufacture of artificial fibers, plastic packaging for liquid food products, films.

2 or HDPE - high density polyethylene with low pressure technology. It is used in the production of shrink films and bags for packaging.

3 or PVC - polyvinyl chloride (PVC) is used in the manufacture of linoleum and plastic windows.

Watch the video to find out more:

4 or LDPE - Low Density High Pressure Polyethylene. Food-grade plastic, from which bags, wrappers and bottles, greenhouse films, packaging containers, toys for children, pipes are made.

5 or PP - polypropylene due to its inertness and heat resistance (it can be kept under hot steam and boiled) is widely used in the production of food packaging. The material is widely used in medicine (disposable syringes, catheters), in the production of household appliances, heat-resistant dishes and plastic pipes for hot water supply.

6 or PS - polystyrene. This type is used to make disposable dishes (cups for food products), inner plastic sheathing of refrigerating devices. When foaming polystyrene foam, a porous insulating material (foam) is obtained, which is widely used in construction and production.

7 or O (Other) - non-recyclable materials (combine a combination of foil, paper and polymer materials) or not included in the previous groups.

One of the ways to determine the grade of plastic in the absence of a sign is to check by combustion. Each material burns in its own way and with a different smell, from which you can determine its appearance.

Adhesives marking

In addition to plastic, plastic adhesive is also marked with symbols, although this designation rarely coincides with the recycling markings. To know how to glue plastics, the following letters are affixed to the adhesives to indicate the materials to be glued:

Designation for plastics (click to enlarge)

• polycarbonate - PC;
• copolymer of acrylonitrile - ABS;
• polypropylene - PP;
• organic glass - PMMA;
• polyethylene - PE;
• polyvinyl chloride - PVC;
• polystyrene - PS;
• polyamide - RA 66;
• polyurethane - PUR.

Often it makes no sense to look for markings on the glue packaging, it is enough to study the instructions in Russian, which clearly explains what types of materials the glue is intended for and how to glue the plastic.

Types of adhesives

Plastic products have many types and are widespread in everyday life, therefore, plastic gluing can be carried out with a wide range of adhesives and different methods.

One of the gluing methods is to soften the surfaces of the parts to be glued with a suitable solvent (dichloroethane for plexiglass or polystyrene), after joining the seam is reliably soldered. In a similar way, you can do it yourself and glue by dissolving small plastic shavings.

Kinds of good adhesives for plastics (click to enlarge)

Liquid

Popular household adhesives are easy to use, there are two types: with a solvent or water-based. The principle of operation of the first is as follows: water or solvent evaporates from the glue applied to the top of the plastic parts, the glue seam dries up with further hardening, due to this, the parts are held tightly.

Such adhesives can glue plastic with porous materials that allow air to pass through, otherwise the water and solvent will not evaporate and the glue will not solidify.

In everyday life and industry, a good liquid PVA glue is known, which is widely used in furniture production for reliable gluing of artificial films to wooden surfaces; in the construction industry, linoleum is often glued to PVA. Other liquid adhesives are made on the basis of rubber resins, in this case, the solvents are methyl acetate, alcohol, acetone.

Contact

The name was given due to the principle of gluing: before gluing the plastic to the plastic, the surfaces of both products to be glued are coated with glue and after 10 - 15 minutes they are firmly pressed against each other. There are two types: with a hardener and without a hardener, the best known brands BF-2 (4), "Moment", rubber glue.

In the video, you will learn how to use contact adhesives:

Adhesives include toxic materials, so at home, before gluing the plastic, it is necessary to ventilate the room.

Reaction adhesives

Distinguish between one-component and two-component types. The former, when applied to the bonded surface, harden very quickly from interaction with oxygen or water vapor. These types include the well-known "Secunda", "Superglue" and other analogs capable of gluing to obtain a rigid and durable seam.

Two-component have separate hardener and hardener. They are bonded before being used for bonding and, after being applied to the bonding surfaces, gradually begin to cure under the influence of ambient conditions and adhere the parts. They are based on various resins, the most famous types are polyurethane, epoxy, polyester.

Friends, good mood to all! As usual, the topic of this article will also deal with computer topics, but from a slightly different angle. Let's talk about what glue plastic to plastic tightly.

This life hack was found by me on the Internet and was applied in practice even at sub-zero temperatures. The person from whom I learned about this method originally used it for gluing laptop cases in the area of ​​the screen hinges. Trust me, this is a very busy part. And the plastic there is such that no super glue takes it at all.

But the matter is fundamentally changed by ordinary table salt. Yes, friends, you just need to make an explosive mixture of super glue and salt. You can, of course, try soda, but after looking at the tests, I came to the conclusion that salt is still better:

So let's start glueing the plastic tightly. We will only show this with an example. car bumper which initially they tried to glue it with different types of adhesives, but everything was useless.

First, the damaged area must be shed degreaser... It is clear that due to the specifics of the crack, it did not work out perfectly. But nevertheless, as it is. Then a pinch of fine salt was taken, which was abundantly sprinkled on the "wound":

After that, we use the usual super glue. By the way, he had never glued the plastic of this bumper before. I tried this and that, there was no result:

But after applying this life hack, the situation has changed radically. Even in spite of the fact that the gluing process took place at a temperature of -2, the plastic finally glued tightly. Of course, visually, the "break" remained visible, since a lot of salt was swollen:

In general, friends, these are the things. If any of you have already tried this method, please unsubscribe in the comments about the successes and materials that you glued together. That's all for now and see you soon!

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 site 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

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 with 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, the specified 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
