Rating of the best adhesives for plastic for 2020

Most of the things around us are made of plastic. And not all of them are durable, some can be quite fragile and break easily. To return such a product to its previous appearance, you will have to try. Gluing two pieces of a plastic object is not easy. The reason is that plastic has a special composition that cannot be joined with ordinary glue. If special welding for plastic products is used in production, then we cannot afford this in everyday life. Therefore, a special adhesive for plastic was created. But here, too, everything is not so simple. Each type of plastic requires a specific type of adhesive, which has its own distinctive properties.

Types of glue for plastic

Since plastic products, unlike ceramics or metal, have a smooth surface, for this reason it is impossible to connect such parts to each other with ordinary glue. The product that connects such parts has a different composition, due to which it dissolves the synthetic polymers that make up the product, thereby connecting the parts. And now on store shelves you can find a large number of different types of glue, which differ in composition and properties. And in order to better understand which product is right for you, you should understand the types of glue.

So, all products can be divided into four main categories. The most common is liquid glue. It has the simplest composition and is easy to use. But besides this, it should be borne in mind that liquid glue is water-based or contains a solvent. After applying such glue, the solvent or water present in the composition will gradually evaporate, at the end of this process, the product will be securely fixed. But it is impossible to use this option with sealed materials, since evaporation will not occur. Even after a long time, the glue will remain liquid and the parts will not bond. But since liquid adhesives will not attack plastic, they are usually used with small objects that will not be subjected to further stress. After application, the product must be left for one day so that the glue can dry completely.

The second product option for working with plastic products is contact adhesive. It can be with or without hardener. Here the glue is applied to the product, after which you need to wait about 10 minutes for the product to dry out a little. After that, it is necessary to press it tightly with another part, so gluing will occur.This option can be used with products subject to stress. But do not forget that contact adhesive is toxic and is not suitable for working with elastic types of plastic.

There is also a reaction type of glue. Here, products are glued under certain conditions, for example, when interacting with atmospheric oxygen or the presence of ultraviolet radiation. Hence the name of the product. This option will provide greater reliability, the connection of the parts will be very strong, which will not separate even with physical impact. This product may consist of one component or two. The first option is the liquid in the container. It just needs to be applied to the surface and connected to another object. This option includes adhesives that we used to call "Superglue". The two-component version has two different containers for the hardener and binder. Before use, they are mixed in a separate container, and then applied to the parts. You can store them after mixing for about 30 minutes.

And the last option is hot melt glue. A glue gun is required to use it. It begins to show its properties at a certain temperature. Each brand has its own. Hot glue is used mostly in handicrafts.

How to choose the right adhesive for plastic

When a plastic object breaks down, usually people do not hesitate and use universal or instant glue. This method is suitable for toys or repairing household items. But there are certain types of adhesives that are designed for specialty plastics. Therefore, a plastic product must be marked. For example, the Latin letters PP say that it is polypropylene, and PVC stands for polyvinyl chloride, PE stands for polyethylene. Such markings do not play a big role in solving everyday issues, but they are very important when it comes to automotive plastics. So it will be seen by what method the repair work should be carried out.

In addition, you should take into account the peculiarity of using the product to be glued. For example, for flexible plastics, it is better to use the liquid version. Especially if the product will be in contact with water or bend. If the parts must be stationary and under high stress, the best option is to work with a reaction adhesive.

A product containing a solvent should be used with great care. It is not suitable for all plastic products, as it can completely ruin the item.

Terms of use

Before starting the bonding process, you should clean the surface from dirt. It will not be superfluous to degrease it with alcohol. To increase the adhesion strength, you can walk over the surface with sandpaper. Much effort is not required, it is only necessary to create some roughness, this will provide better grip. Do not apply a large amount of glue, it is not desirable for it to go beyond the working area. After that, you should smoothly but firmly squeeze the parts. If you are using a two-component product, mixing should be done before application.

Now let's talk about the rules for working with certain types of glue. When working with liquid glue, it should be applied to the surface of one object, and then firmly connected to another, if necessary, use a load for better bonding. Also, sometimes the product is applied to both products, they wait for complete drying, and then they do the above procedure. Drying of such glue does not occur immediately, so in the process you can correct the parts and set them in the desired position.

If you work with a reactive one-component adhesive, then apply it to the surface of one part and immediately apply the second. The reaction here is very fast, therefore it is also called second.If the work is to be done with a two-component product, then it should be mixed according to the proportions indicated on the package, after which it is applied to two parts, and they are connected.

When working with hot melt glue, you must insert the glue stick into the gun, wait for it to heat up. After that, a portion of the glue is applied to the parts and fastened together. You need to work here very quickly and accurately, since the glue hardens very quickly.
