Which glue is best for plastic and paper. What glue to glue cardboard to cardboard and other materials

Plastic products are widespread in everyday life. In the event of a breakdown, you need to know what kind of plastic adhesive you need for repair. To make the gluing result strong and safe, we advise you to familiarize yourself with the types of plastic and the rules for selecting an adhesive.

What does marking on plastic mean?

Since some adhesives may dissolve rather than bond the plastic, it is advisable to examine the markings on the broken product. The plastic type icon looks like a triangle formed by arrows (recycling symbol). Inside it there are numbers from 1 to 7, and below there is an inscription. These identification marks determine the belonging of the material to one or another type of plastic, which will allow you to choose the right glue.

What types of plastic exist:

• 1 (PET) - stands for polyethylene terephthalate. It is used to produce food packaging for liquid products.
• 2 (HDPE) - high density polyethylene, intended for the production of packaging and shrink films.
• 3 (PVC) - polyvinyl chloride, better known as PVC. Plastic windows, linoleum, etc. are made from it.
• 4 (LDPE) - low density polyethylene, from which toys for children, pipes, bottles, packaging containers are made.
• 5 (PP) - polypropylene, heat-resistant material. It is used for the production of food packaging, medical disposable instruments, household appliances, pipes, thermal dishes.
• 6 (PS) - polystyrene. Disposable tableware is made of it. Expanded polystyrene is widely used in construction.
• 7 (O) - This type of plastic is not recyclable, consists of a mixture of polymers, paper, foil.

Adhesive marking

The main difficulty is that the adhesive labeling does not match the plastic recycling symbols.

How is adhesive for plastic labeled:

• PE - polyethylene;
• PC - polycarbonate;
• PP - polypropylene;
• PVC - polyvinyl chloride;
• PMMA - organic glass;
• PUR - polyurethane;
• PA 66 is a polyamide.

Sometimes it is easier to find a clear instruction in Russian than a marking icon. But if there are no recommendations on the packaging, then the designations will help you make the right choice.

Types of glue

Plastic has low adhesion due to its smoothness, therefore it is more difficult to glue it than other materials. In industry, such products are held together by welding. At home, this method is not used, but you can pick up a good glue. The principle of operation of the composition is as follows: it dissolves the surface, and with strong squeezing, the parts are connected. Therefore, the main component of plastic glue is a solvent for synthetic polymers. For viscosity, the composition contains liquid polystyrene.

Liquid glue for plastic and Moment plastic

The group of adhesives for plastics can be divided into the following types:

1. Hot glue... It is a solid glue stick. They must be heated before use. There are special, there are also types of glue for use without a gun. Such a composition is suitable for small jobs, since it does not have a particular bond strength.
2. Contact... It is often sold complete with a hardener, which must be mixed with the bulk in the proportions indicated on the pack. This type of glue can firmly glue plastic, but there is one drawback: the product is toxic. Personal protective equipment must be worn. For a better fastening of the parts, after applying the glue, you need to wait 10 minutes, and only then squeeze them firmly.
3. is water-based and considered the least effective bonding method. It dries up for a long time (at least a day). It is used to repair small items that are not subject to increased stress. But liquid glue samples do not deform plastic, this is very important for working with small parts.
4. Reactionary- a reliable and affordable glue for plastic. There are several types of such compounds: some are designed to work under water, others freeze under the influence of ultraviolet radiation, and still others work in the open air. There are one-component and two-component.

Advice! Do not use toxic contact glue to glue children's toys.

Product examples

What can be found on the shelves of hardware and hardware stores:

1. « Moment plastic" is a type of glue that connects many types of plastics. It has a transparent base, sets quickly and forms a strong bond. It is a water and heat resistant compound. However, it contains toxic substances and is not used to repair products that come into contact with food or skin.
2. "Super Moment"- second glue.
3. - epoxy adhesive, hardens in 20 seconds. Simple and easy-to-use composition.
4. "" Is a brand offering several types of adhesives for plastics. Among them, adhesive sealant for transparent plastic, the composition Plus for PVC, PMMA- adhesive for polystyrene and acrylic surfaces.
5. « Second"- super glue for hard plastics. One of the fastest-acting formulations.
6. For minor car repairs, special car sealants for plastic are sold.
7. Rexant - hot melt glue, available in the form of rods. It can be transparent or colored (to mask joints if colored parts are connected).
8. Akfix HT300 - heat and water resistant composition. Withstands temperatures up to +300 degrees. This adhesive contains silicone. It reacts to humid air.

This is far from the entire assortment offered by the adhesive industry. This is not to say that some kind of glue is better or worse. Each train is designed for specific types of work. Read the instructions carefully and follow all recommendations.

How to glue plastic

The type of plastic is established, the desired glue is selected. How to glue plastic items correctly:

1. Details should be cleaned. If necessary, degrease the item with soapy water or ethyl alcohol. A clean surface will have more adhesion and the items will be easier to glue.
2. It won't hurt to lightly sand the surfaces to roughen them. This will help the glue stick better.
3. Two-component compounds are mixed only after surface preparation.
4. If the parts are covered with glue with a brush, then an object with artificial bristles is taken.
5. The adhesive is applied in such an amount that, when compressed, its excess does not come to the surface.
6. You need to squeeze objects together tightly, but carefully.
7. The adhesion time of the materials depends on the selected adhesive.

Advice! Use a needle to glue a thin crack.

Sometimes you need to attach a wide variety of materials to plastic: wood, glass or metal. In this case, the glue must take into account the characteristics of the two surfaces to be joined, and not just the plastic.

Glue Super moment

Work tips with plastic:

1. For outdoor use, waterproof glue is used.
2. Despite the high temperature that the glue can withstand, the plastic objects themselves should not be exposed to it.
3. When working with contact adhesive, it is necessary to ventilate the room.
4. The best adhesive for marking 7 (O) is epoxy. This type is also suitable for polystyrene.
5. If there is no marking on the product, then start from this: for plastic toys and artificial glass, mainly polystyrene is taken; for bottles, buckets and boxes, glue designed for polypropylene and polyethylene is suitable.

Take the time to study the labeling of plastic products and glue. If the repair of small toys like "Lego" is a simple process, then for more serious work the usual Secunda glue may not be suitable.

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 application.

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.

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.

You will definitely take this trick into your arsenal if you did not know it before. It's about how to very reliably glue plastic or plastic parts with ordinary second-hand glue, using one small secret, which more than 10 times increases the strength of the connection of two parts.

What's the trick?

So, the secret is that around the seam of the parts to be glued, we will apply ordinary soda with superglue. The result is the strongest bulge around the seam.
The fact is that cyanoacrylates, which make up the glue, interact with soda. They interact, and are not an ordinary filler. When these two components are mixed, an instant reaction occurs and a very strong composition is obtained with which it is quite possible to glue not only plastics, but also metals. A kind of cold welding. Seconds glue alone is not half as strong when used alone. Not surprisingly, everyone did a poor job of holding up and falling apart. But with the use of this technology, this will no longer happen.

It will take

• Any super or second glue.
• Baking soda.

We glue the plastic

Let's get started. The sleeve into which the screw is being screwed has broken off. And, accordingly, I will now restore all this.
In the beginning, everything is as usual. Lubricate the place with glue.

One and the second part.

Let's put them together.

Now soda comes into play. When the parts come into contact, excess glue is squeezed out, it must be sprinkled with soda abundantly.

After 5 seconds, the excess can be blown off.

Then pour plenty of superglue around the crack and then fill it with baking soda again.

Blow off the excess again.

We repeat the process one more time.

Sprinkle generously.

As a result, a solid sludge formed around the sleeve, which will securely hold everything.

Although everything has hardened before our eyes, it is recommended to let it stand for about 24 hours before using the product.

Pros and cons of the method

Pros:

• Instant hardening. Even large drops freeze immediately.
• As a result, a very strong monolith is obtained.
• Adheres to almost any plastic.
• You can even glue holes and holes.

Minuses:

• Instant hardening can act as a negative factor, due to the fact that the composition cannot be poured into the center of the parts to be glued.
• The reaction occurs with the release of heat, which in some cases can serve negatively.
• Unfortunately, such a composition can only be applied to the surface, but there are times when there is no way to get there.

I especially recommend taking this recipe for a note to motorists, since I myself have glued dashboards and light filter glasses in this way more than once. Keeps it tight!

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.
