Types of glue for plastic

To make it easier to find high-quality glue, you should familiarize yourself with the popular representatives that are most often found in stores and on the market. Correctly selected adhesive will reliably stick to any surface and will last for a maximum period.

It is important to know that the plastic itself has poor adhesion because it has a smooth surface. This greatly affects the quality and reliability of gluing.

In industrial enterprises, special welding is often used, as it allows elements to be connected more reliably and for a long time.

The main principle of the glue is that the surface dissolves and, after a strong blow, is crushed into a monolithic structure. Therefore, any plastic is based on a special solvent, and the composition includes wild polystyrene to ensure viscosity.

Hot melt adhesive for plastic

Bonding with heated plastic rods is not strong. Hot melt adhesives are used to fill chips and voids on plastic surfaces. Due to poor adhesion, thermal bars are not suitable for parts subject to stress. Do not use rods to glue small parts or broken flat panels.

The advantage of this option is that the glue is easily applied to the surface. This option is ideal for small operations.

Contact adhesive for plastic

This type of plastic parts can be easily glued and the adhesion quality will be high. There are two types of contact adhesives: with and without hardener. Applying both types involves the same steps. Glue is applied to one or both parts to be joined. They wait some time for the composition to stabilize, usually 10-15 minutes, then the parts are pressed against each other.

This type of composition is equipped with toxic elements, so work must be carried out in compliance with safety precautions, good ventilation is created, and substances do not enter the skin.

Glue is applied to one or both parts to be joined.

Liquid glue for plastic

Liquid adhesives are the easiest to use and therefore the most popular. Water-based and thinner versions are available. Their operating principle is the natural evaporation of solvents or water, depending on the components used. After the process is completed, hardening occurs and a reliable seam is created.

As a result, they should not be used on sealed objects; evaporation may not occur in this case. Among them, PVA, known to many, stands out, suitable for porous surfaces, with which you can stick plastic films on furniture. Dichloroethane is also of this type, but its use is harmful to health, so it is more often used in industry.

Liquid adhesives are the easiest to use and therefore the most popular.

Reaction glue for plastic

Reactive adhesives are reliable and affordable. Some reactive adhesives require external drying of the parts to be glued, others require the presence of ultraviolet rays, and others require water. All produced reaction adhesives are divided into 2 groups: one-component and two-component. Adhesives include polyesters, epoxy resins and polyurethane.

Edible glue

Such products do not emit toxic substances, which allows them to be used for gluing household items. Edible glue is in great demand among buyers. It does not cause poisoning or allergies, which is important if there are small children at home.

Benefits of Metal Adhesive in Achieving Production Goals

At all times, different methods were used to connect two metals together. This includes riveting, welding, cold welding, and recently another method has emerged - gluing. The chemical industry has moved forward, and many components have emerged that can tightly join two pieces of metal.

This method is better than the previous ones. You can buy iron glue at any hardware store. Without much skill, connect two elements, and they will hold firmly. No welding, electricity or welding machines required. Only a small tube.

Using a welding machine you can join metal to metal, but you need a good machine and uninterrupted electricity. In addition, you need to know how to use it. You can buy glue at a hardware store, and, following safety precautions, connect the necessary elements according to the instructions. This is the advantage of this method.

The best waterproof adhesives

Waterproof compounds are used to join parts that are exposed to moisture. For example, this glue is used to connect pipes made of PVC and other plastic materials in the bathroom or kitchen.

Moment Crystal

This clear adhesive is resistant to moisture, dilute acids and low temperatures. It can be used in construction and repair work, as well as in embroidery. It can be used for gluing metal parts, plastic products, as well as plexiglass, polystyrene, soft and hard PVC, and is also suitable for processing glass, rubber, cardboard and other materials.

When working with Moment Crystal, it is desirable that the room is ventilated and there are no children or animals nearby. This is necessary due to the unpleasant odor this product has. In addition, gloves and a respiratory mask must be used while working. Opened adhesive should be stored in a dry and warm place, away from fire and heating devices.

Because it can easily ignite. In addition, if the product was transported or stored in a cold place, you must wait until it “reaches” room temperature before starting work. When using Moment Crystal, make sure products are dry and clean.

After this, apply the product to both parts of the product and connect them together. After 15 minutes, squeeze them well. The glued product will be ready for use within a day.

Instructions - glue the plastic together

Let's look at the procedure for performing the work using the example of one of the decorative plastic parts of a scooter (motor scooter), which is marked “ABS+PC”.

This symbol indicates that the part is made from a mixture of ABS plastic and polycarbonate. This combination is widely used for the manufacture of bumpers, all kinds of decorative trims and other parts.

You can glue a crack in this type of plastic using universal two-component epoxy glue EDP (Russia).

The glue itself is prepared by thoroughly mixing the resin and hardener in the ratio specified in the instructions. As a rule, take 1 part hardener for 10 parts of epoxy resin.

Work order:

1. Preparation of bonded surfaces. Parts must be cleaned of dust, oil and other contaminants. Gluing is done from the inside so that the adhesive seam is invisible. For better adhesion, it is recommended to lightly treat the surface with fine sandpaper, degrease with a solvent (it is better to use ethyl alcohol), and dry;
2. Fixation of parts to be glued. Unlike contact adhesives, which set instantly, epoxy resin cures within a few hours and does not require strong compression. It is enough to ensure the immobility of the two parts by grabbing them with clamps, clothespins or other available means.
3. Application of epoxy composition. The joint is carefully coated with a thin layer of epoxy so that the glue is applied to each side of the crack. Then a layer of fiberglass is placed on the glue. Next, apply another layer of glue.
4. Bonding time. The glued part is left to dry until completely set in a room with good ventilation. This takes 24 hours.

VIDEO INSTRUCTION

What else can you firmly glue plastic with?

Plastic is considered one of the most “capricious” materials in terms of gluing with other surfaces, but if you choose the right glue, then plastic can be firmly glued to metal, concrete, and wood.

It is recommended to use epoxy, polyurethane and phenolic rubber adhesives as glue for connecting polymer to metal. An excellent option would be cold welding Poxipol.

Using UHU Twist & Glue, most plastics can be bonded to wood, glass, ceramics and other materials.

Instant cyanoacrylate adhesives allow you to join plastic to metal, wood and rubber in seconds.

In everyday life, many have encountered such a problem as broken plastic products. These items can rarely be repaired with your own hands; it is safer to seal them. You can decide how to glue plastic tightly by considering the best adhesives for various types and gluing technology.

Required properties of glass adhesive

Before gluing glass, it is important to purchase a high-quality composition.
Let's figure out what technical characteristics a special product should have for this purpose. So, the main requirements for the properties of this material are:

• improved adhesion to different types of coatings;
• transparency and invisibility of the glue on the treated surface;
• fast setting;
• viscosity, some ductility, elasticity;
• resistance to temperature changes, as well as to conditions of high humidity;
• safety for human use;
• Possibility of storing the product with the condition of further use after the first opening.

Interestingly, not every type of adhesive combines such characteristics. For example, too cheap glass glue often does not have the listed features. For this reason, craftsmen recommend paying attention to more expensive products. After all, they are, as a rule, of higher quality and meet consumer expectations.

Epoxy resin

If something needs to be glued together for years, epoxy resin is the best option. And regardless of the brand chosen, each of them shows excellent gluing results. The hardeners contained in epoxy resin are resistant to all types of influence, including acids. Many craftsmen also make jewelry from epoxy resin. They place a flower or any other object in a mold and fill it with resin. The resulting pendant can faithfully serve its owner for many years.

Adhesive for glass products: types

Clear glass adhesive is not uncommon. The consumer market offers a wide range of adhesive materials for various needs. It’s easy to get confused in such a comprehensive range if you don’t understand their features and scope of application at all.

As you can see, in order to glue glass, it is important to navigate the adhesive materials specially designed for this. In order to help make the right choice of transparent glass adhesive, the article below presents its most popular types with detailed characteristics.

Polyurethane based

One of the optimal adhesive materials that helps glue glass together is a polyurethane mixture. Suitable for working with smooth surfaces. This fact explains the popularity of the product for interacting with glass surfaces.

Conventionally, these goods can be divided into two main categories:

1. Single-component. They attract attention because they are immediately ready for use. After all, the mixture eliminates the addition of additional components.
2. Two-component. They are characterized by increased flexibility regarding the time of complete polymerization. The exact period depends on the amount of hardener in the product. The main advantage of the product is its ability to be restored.

A polyurethane adhesive mixture is combined from resins and active substances that provide viscosity, are responsible for consistency and for the speed of complete drying. Composite additives are used to strengthen the seam.

Cyanoacrylate

Glass gluing can also be done using cyanoacrylate type glue. Positioned by manufacturers as a universal remedy. In addition, these types of glue can be used in the production of electrical appliances. There is both a transparent mixture and a composition with a yellowish tint.

The main advantages are:

• rational cost;
• liquefied consistency;
• fast setting;
• increased seam strength.

Manufacturers of cyanoacrylate glue made sure that the use of the product was as comfortable as possible for the consumer. So, it comes in tubes made of plastic or aluminum. In this case, the product does not have to be used at once. Just close the tube tightly. Then it is guaranteed to last a long time without any changes until further use.

In addition, cyacrine compositions are also found in gel format. At room temperature, the mixture begins to harden in literally three seconds. You should only handle this adhesive mixture with gloves, because getting it on your hands can cause serious skin burns. Before purchasing transparent glue, read the instructions, because this adhesive is compatible with certain types of plastic.

PVA

Glass can also be glued using PVA. Polyvinyl acetate-based glue is found in any home and is often used in everyday life. Naturally, the effectiveness of gluing glass is questionable, because PVA does not have a high enough degree of adhesion.

Another disadvantage is that some of these products can leave marks on the seams when gluing. The main advantage of PVA when gluing glass is, of course, its availability. This composition can be easily found in almost all stores, and at a low price.

Heat resistant

Heat-resistant transparent glass adhesive is intended for gluing those objects and surfaces that will subsequently be exposed to elevated temperatures.

For example, heat-resistant adhesive can be used for bonding:

1. Ovens, electric kettles. When restoring kitchen stoves.
2. For other equipment with glass inserts.

The advantage of the adhesive is that the created adhesive seam will not melt when exposed to elevated temperatures. This effect was achieved thanks to the addition of special amplifiers as components of the product.

Optic

The main purpose of this glue is gluing optical devices. In particular, it is used by manufacturers of photographic equipment and other devices that require full transmission of ultraviolet rays.

This transparent adhesive is extremely rarely used in domestic conditions. Most often it is used by professionals, which means finding a product on free sale is a difficult task. And, naturally, the disadvantage of such products is their rather high cost, which is explained by the high cost of the components of the composition.

Polymer based

It fully sets and dries primarily due to exposure to ultraviolet rays. Allows you to firmly glue glass fragments. This clear adhesive must be used wisely and only on certain surfaces. At least one of the glasses must be transparent to provide light access.

In order for the surfaces to be glued to fully adhere to each other, they must be placed under a specially designed lamp, which will ensure complete hardening. Among the advantages of this type of glue are:

• complete transparency of seams;
• tolerance of high air temperatures, high humidity;
• as well as excellent tolerance to mechanical loads.

All users cite the relatively long drying time of the material as an absolute disadvantage.

Silicone

In addition, glass can be glued using a composition such as silicone glass adhesive. It is a special transparent mixture of high molecular weight polymers with the addition of several components. Thanks to them, such adhesives are characterized by resistance to a variety of bacteriological environments.

Silicone is an environmentally friendly material, so it can even be used in the food industry. The exact drying time depends on the complete list of components of the product, humidity and air temperature in the room where the work is being carried out.

How to choose the right glue for plastic

When choosing an adhesive, you need to consider the type of plastic. To do this, each product is marked in the form of a triangle with arrows:

• PETE is the most common polyethylene, a thermoplastic used to make food containers and packaging materials. It is often used in the manufacture of electrical and radio engineering elements and cosmetic containers.
• PVC is plasticized polyvinyl chloride, a universal material used in the production of the vast majority of goods: furniture, building materials, various parts, food containers.
• LDPE is a thermoplastic material that is considered a good thermal insulator. These include tubes, packaging, toys.
• PP is strong, durable, the cheapest polypropylene and is considered the cheapest and most popular plastic. It is used in the manufacture of sewer pipes, automobile parts, and various tools. Excellent resistance to aggressive substances and extreme temperatures.
• Polystyrene PS is a thermoplastic polymer that is resistant to chemicals and moisture. One of the most common types of plastic, used for thermal insulation of furniture, dishes and linings.
• Other and other types of plastics to which various polymer elements are added. Not reusable. It is characterized by high strength.

The tube must be sealed, undamaged, and contain detailed information and instructions. To repair toys, you should purchase a solution based on BF glue.

When choosing an adhesive, you should take into account the material on which the plastic is glued.

When purchasing glue, it is important to consider the material on which the plastic is attached: paper, leather, metal, wood, etc. If the product is intended to be used outdoors or in places with high humidity (kitchen, bathroom, shower), moisture-resistant types are used. When working with contact adhesive, ensure ventilation and ventilation.

One-component and two-component adhesives for plastics have their own markings in the form of letter abbreviations. For example, PPMA (plexiglass), PP (polypropylene), PA 66 (polyamide), etc. For the average consumer, these designations do not have much meaning, since any adhesive for plastics has instructions indicating which types of plastics are suitable for gluing.

What glue to use to glue plastic to: plastic, metal, chipboard, tile, concrete

The modern world is unthinkable without plastic products; the lightweight material is used everywhere: construction, decorations, furniture, dishes, decorative elements, household appliances. Polymer products do not rust, are beautiful, but not always durable. Therefore, breakage of plastic items occurs frequently; every time something is dropped, the problem arises of how to restore the broken product.

Universal glue

Don’t be upset - there are no eternal objects, and you shouldn’t throw away a broken thing. Today there are no problems in repairing any material, even polymer. You just need to think about how to glue your favorite thing together.

How to glue plastic tightly at home

Gluing plastic is not that difficult. Buy glue for plastic and follow our tips:

• Remove grease stains. Before you start gluing, degrease the work surfaces with a suitable detergent, alcohol or just soapy water. Dry or dry thoroughly. Do not touch the plastic with bare hands to avoid leaving oil stains.
• Sand the surface. For better adhesion of the glue, plastic surfaces must be slightly roughened. Sand the bonding area with sandpaper or sandpaper.
• Mix ingredients as needed. If you are using epoxy glue, you will need to mix the ingredients yourself in the correct proportions.
• Apply glue carefully. Apply glue to the plastic with a synthetic brush. For small details, use a toothpick or the tip of a needle. Try to apply the glue in a thin layer so that it does not spread when further squeezing.

Read the instructions carefully before starting work. Many types of plastic adhesives require the adhesive-coated surfaces to be pre-cured before pressing them, while others require them to be held at a specific temperature. The more carefully you follow the manufacturer's recommendations, the better the result will be.

• Press the pieces together. The reliability of the connection largely depends on the force with which the parts are pressed against each other. Try to do this with force, but not sharply, squeezing the parts strictly perpendicular to the surfaces being glued. Use clamps or rubber bands to hold the pieces until the glue is completely dry.
• Remove any remaining glue. Clean the glued parts from drops of glue using a special tool or any alcohol. Cyanoacrylate glue can be easily removed with acetone, but be careful not to damage the plastic.

Rules for working with glue

Many adhesive compositions contain toxic or harmful compounds that are released during curing. Before gluing plastic to metal, you need to take care to follow safety rules so as not to harm yourself and others. To do this you should:

• ensure active ventilation of the room with removal of at least three times the volume of air outside within an hour;
• when working with glue, constantly wear a respirator of the appropriate protection class to protect the respiratory system;
• wear protective gloves to prevent glue from contacting the skin of your hands;
• Protect your eyes with goggles or a transparent mask;
• To store glue, choose a place inaccessible to children and pets.

By following simple recommendations, you will minimize the risk of poisoning from toxic components.

How to achieve maximum effect when gluing plastic parts

To achieve the best result, you should study the recommendations of specialists. They highlight the following points:

• The need to correctly determine the type of plastic;
• Strict adherence to manufacturer's instructions;
• it is necessary to maintain the specified time until the gluing process is completed;
• If there are no marks, you can apply glue to an inconspicuous area and see the reaction of the material.

it is necessary to maintain the specified time until the gluing process is completed.

Determining the type of plastic

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

Most often, the manufacturer labels 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 indication of a brand is the letter symbols inside or next to the triangle. Knowing these designations, you can determine the type of plastic and then the appropriate plastic adhesive for it.

Marking

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

2 or HDPE - high-density polyethylene using low-pressure technology. Used in the production of shrink film and packaging bags.

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

4 or LDPE - low-density polyethylene using high-pressure technology. Food grade plastic is used to make bags, wrappers and bottles, greenhouse film, packaging containers, toys for children, and pipes.

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 tableware and plastic pipes for hot water supply.

6 or PS - polystyrene. Disposable tableware (cups for food products) and the internal plastic lining of refrigeration devices are made from this type. By foaming polystyrene foam, a porous insulating material (foam plastic) is obtained, widely used in construction and manufacturing.

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

One way to determine the brand of plastic in the absence of a sign is to test it by burning. Each material burns differently and with a different smell, from which you can determine its type.

What affects the reliability of gluing

Not many people know that adhesion strength depends on many factors. To avoid mistakes, you need to follow some rules. There are several conditions for successful gluing:

• Selection of adhesive suitable for a specific plastic;
• The compression and hardening times must be observed;
• Prepare the surface, remove dirt, degrease and smooth. The parts must be immediately pressed into the correct position.

To avoid mistakes, you need to follow some rules.

Criterias of choice

To choose the right adhesive for gluing metal to metal or other materials, you need to evaluate:

• dimensions of the treated surface;
• properties and composition of the connecting agent;
• drying speed;
• physical and mechanical parameters.

Ask a Question

It is important to consider the differences between the surfaces being joined. If the fastening occurs between solid materials, it is better to purchase a hard glue; if attached to an elastic one, it is better to purchase liquid or soft glue.

Gluing glass to glass: instructions

First, prepare the necessary parts, clear glass glue and put on gloves. Next, proceed to the actual work:

1. We clean the coatings of the parts to be glued and wait until they dry.
2. Apply transparent glue to one of the parts that need to be joined.
3. Immediately we press them to each other. There is no need to wait some time before compressing, because setting occurs relatively quickly.
4. We wait until the adhesive layer dries.

In fact, the main thing in such a process is maximum caution when working with sharp corners of glass. You also need to focus on the instructions from the manufacturers, who may note some important nuances of correct work with the produced compounds.

How to glue glass to metal?

Don't know how to glue glass to metal? Everything is also simple here if you manage to choose the right transparent glue for glass and metal. So, you will need to purchase UV glue or another product with a gel consistency. This is necessary so that the seam remains in the right place and does not spread over the surface being treated.

Both glass and metal surfaces need to be degreased. In addition, in order to glue glass and metal, they should be heated to forty degrees. This same process will help dry the parts and also remove any remaining adhesive from the previous one.

We place the seam horizontally, and apply transparent glass glue to the part. We press using suction cups or a magnet for high-quality polymerization. We wait until the adhesive has completely cured according to the time specified in the instructions for the product.

Bonding glass to wood

Now let's look at the question of how to glue glass to wood. According to the algorithm of actions, you can safely focus on the principles of bonding glass to metal.

First of all, you need to clean the coating and sand the wood material. This will ensure a more even seam, and, accordingly, better quality when gluing the wood onto the glass. It is recommended to choose a paste or gel based adhesive.

Types and chemical composition of silicone adhesives

All silicone adhesives and sealants, regardless of type and purpose, have fundamentally the same composition. They are based on various organosilicon rubbers; today, silicone and fluorosiloxane rubbers are most often used. When exposed to air, these rubbers interact with the moisture contained in it and vulcanize (polymerize) - becoming hard and elastic.

However, to ensure full quality as an adhesive or sealant, these compounds are modified - one or another organic compound is added to their molecules, which, when in a sealed container, prevents the polymerization of silicone rubbers. When exposed to air, these compounds react with water molecules (they are always present in the air), detach from the silicone elastomers, and, as chemists say, are expelled from the glue mass. As a result of this reaction, rubber molecules react with each other - vulcanization (or polymerization) occurs, which results in the formation of a network structure that provides all the properties of silicone adhesives and sealants described above.

Today, all silicone adhesives and sealants are divided into two large groups according to the type of organic compound that prevents polymerization in the absence of air access:

• Acidic (the name of the substances of their composition always contains the word “acetoxy”, for example, acetoxy silicone) - elastomer molecules are connected to molecules of ordinary acetic acid;
• Neutral (their name often contains the word “alkoxy” or “methoxy”) - elastomer molecules are combined with molecules of various alcohols and oximes.

Acidic silicone adhesives and sealants are the most common today, due to their affordable cost and sufficient efficiency to perform most jobs. When used, this glue releases acetic acid, which is immediately noticeable by its characteristic odor. Among the disadvantages of this type of adhesive, it should be noted the qualities associated with the release of acid - they can cause corrosion of metals and have a negative effect on some materials.

Neutral silicone adhesives and sealants are somewhat more expensive, but they do not have the disadvantages inherent in their acidic counterparts - they do not cause corrosion and can be freely used for gluing different materials. When used, such adhesives release alcohols and other substances that do not have specific odors. However, it is worth considering that silicone adhesives containing oximes are potentially dangerous, since substances in this group have carcinogenic properties, and frequent contact with them increases the risk of cancer.

In addition to rubber, silicone adhesives and sealants may also contain other substances - plasticizers, modifiers, antiseptics, fungicides, catalysts, dyes, UV filters, metals to increase heat resistance, etc. By changing the composition, you can achieve different properties of adhesives and sealants, so today the market is ready to offer a huge amount of these materials for various purposes.
