Rating of the best plastic adhesives for 2022

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 former appearance, you will have to try. Gluing two parts of a plastic object together is not easy. The reason is that plastic has a special composition that cannot be joined with ordinary glue. If the production uses special welding for plastic products, then in everyday life we ​​cannot afford this. Therefore, a special adhesive for plastic was created. But even here everything is not so simple. Each type of plastic requires a certain 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 the shelves of stores you can find a large number of different options for 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 an adhesive, 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 because liquid adhesives won't attack plastic, they're usually used on small items that won't be stressed later. 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 a contact adhesive. It can be with or without hardener. Here the glue is applied to the product, after which you have to wait about 10 minutes for the product to dry a little. After that, it is necessary to press it tightly with another part, and gluing will occur. This option can be used with products subjected to stress. But do not forget that the 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 bonded under certain conditions, for example, when interacting with oxygen in the air or in 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 occur even under physical impact. This product may consist of one or two components. The first option is a liquid in a container. It just needs to be applied to the surface and connected to another object. This option includes adhesives, which we used to call "Super Glue". The two-component option consists of two different containers where the hardener and binder are located. 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 glue. You need a glue gun to use it. It begins to show its properties at a certain temperature. Each brand has its own. Hot glue is used mostly in needlework.

How to choose the right glue for plastic

When a plastic item breaks, usually people don't think twice and use an all-purpose or instant adhesive. This method is suitable for toys or repairing household items. But there are certain types of glue that are designed for special plastics. Therefore, a plastic product must be marked. For example, the Latin letters PP indicate that it is polypropylene, and PVC indicates polyvinyl chloride, PE means polyethylene. Such markings do not play a big role in solving everyday issues, but they are very important when it comes to automotive plastic. This will give you an idea of ​​how the repairs should be done.

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

A product containing a solvent must 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 gluing process, the surface should be cleaned of dirt. It will not be superfluous to degrease it with alcohol. To increase the bonding strength, you can walk along the surface with sandpaper. It does not require much effort, it is only necessary to create some kind of roughness, this will provide better grip. Do not apply a large amount of glue, it is not desirable that it goes beyond the working area. After that, gently but firmly squeeze the parts.If you are using a two component product then mixing should be done prior to 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 fastening. Also, sometimes the product is applied to both products, they wait for complete drying, and then the above procedure is performed. The 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 it must be applied to the surface of one part and immediately applied to the second. The reaction here is very fast, so it is also called a second. If work is to be done with a two-component product, then it should be mixed in the proportions indicated on the package, after which it is applied to two parts and they are connected.

When working with hot glue, it is necessary to 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 fasten them. You need to work here very quickly and carefully, because the glue hardens very quickly.
