It is sometimes very necessary to glue plastic. Moreover, most often things are not breaking cheap, they are much easier and more economical to glue them than to acquire new ones. In this article we will tell you how to glue plastic products.

How to glue plastic depending on its type?

Please note that in order to choose the right glue, it is necessary to determine the type of plastic or plastic. How can I do that? Most often, certain designations are indicated on packages with goods. For example, PS means polystyrene. In this case, epoxy acrylic or cyanoacrylate is most often used, which is sold under the guise of a superhylle, where cyanoacrylate is written in small letters.

There are also other types of plastics, such as polyethylene and polypropylene. They are indicated by these letters: HDPE, LDPE, PP. In this case, cyanoacrylate can be absolutely ineffective. There is a plastic with the abbreviation ABS. This is nothing but a mixture of plastic resins. It is quite easy to glue with epoxy resin or cyanacrilatic glue.

Types of plastics and glue:

What to do if nothing is written on the package? In this case, you must carefully look at the details. For example, plastic is quite plastic, soft, but fragile at the same time. A children's designer of Lego is made from it. This is ABS.
Polystyrol is used for the manufacture of artificial glass, cheap children's toys.
Polystyrene is used in pretty good quality in the manufacture of artificial glass, Chinese -made toys, which are very cheap. That is, it is a brittle plastic. What plastic is made of CD covers.
In the case of ABS plastic, that is, from which the Lego designer is made, epoxy resin should be taken as adhesive. If this is polystyrene, then gluing should be carried out using a polycet. Incorrect choice of glue can cause its non -effectiveness.

How to glue plastic: Types of glue

After you have determined the type of plastic, you must approach the choice of glue. Here also do not stoop and carefully evaluate the composition. One of the most common options is thermic mushrooms. It is usually sold in the form of sticks that are inserted into a thermal pistol.

Under the influence of electricity, the spiral heats up and melts adhesive sticks, turning the mixture into a liquid state. It is this adhesive mass that must be applied to the surface and glued. After cooling, the glue provides good resistance and strength.

Kinds:

Liquid glue. It is based on some kind of solvent. It can be water, special alcohol or other organic solvent. The essence of the work of such glue is that in a liquid state this substance is not adhesive, but after evaporation of the solvent hardens.
Reaction glue. Most often sold in the form of two bottles, which must be mixed before gluing. Most often it is also called liquid welding. Before carrying out manipulations, the hardener is mixed with the glue itself, until plastic mass is obtained. After that, applied to glued surfaces and pressed. After the hardener freezes, the glue becomes very solid. In this way, plastic and metal parts are most often glued when car repair, as well as in order to put the patch on the tires.
Contact glue. It is very well suited for repairing plastic parts. In order for it to work, it is necessary to apply it on two surfaces, leave it for 5-10 minutes separately, and then just press. As a result of the contact of the layers of glue, it adheres. Please note that in the composition of contact glue very often are very toxic substances, so in the process it is necessary to ventilate the room. After glue, you need to close the door, open the window and let the glue disappear.
It is worth noting that if plastic is glued with metal or glass objects, it is necessary to choose a completely different glue.

What depends on the quality of gluing objects:

From the properties of plastic itself. That is, it is an indicator of solubility, a certain structure of plastic
From the properties of glue, how well it shows adhesive properties, sticks to the surface
From compliance with the instructions
From the features of the plastic product itself. That is, from how you are going to use it after gluing

Popular brands for plastic

Popular types of glue for gluing plastics:

The most common is epoxy or polyurethane glue. As indicated above, it consists of two parts. Accordingly, for gluing, you will have to try a bit, mixing individual components, to obtain the adhesive composition. Sold in 2 bottles. An equal amount of the contents of the first and second bottle is squeezed to the surface, thoroughly mixed, quickly applied to the surface and fixed for a short time. For complete solidification, it will take about 24 hours.
The main advantage in the speed of action and rather high efficiency. But this option is not suitable if the products are flexible and it will also need to be bent during operation. Because such polyurethane glue cracks very quickly and crumbles from the surface. Such gluing is permissible only when using static parts.
If this option is not suitable for you or the part is quite flexible, we recommend funds based on certain solvents Or the solvent itself. Quite often, glue is prepared from plastic chips, adding a small amount of solvent, leaving for a while. As a result, the solvent dissolves plastic, turning into liquid porridge. It is this porridge that needs to be applied to glued parts and combined with each other. After the solvent dries, the plastic remains in its original form.
The most interesting thing is that some details are very poorly lendered to gluing, only the so -called soldering is suitable for them. In this case, a special device is used, as well as a reinforcing mesh, in order to press the glued surfaces and connect.

How to glue plastic with wood, metal, glass?

We recommend choosing glue, focusing on the conditions in which this part will be operated.

Tips:

If you need a rather stiff coup, but the part will not bend, in this case we recommend that the well -known supergli based on cyanoacrylate, as well as glue the moment. This kind of adhesive compositions easily cope with gesture compounds.
In order to glue flexible parts and parts that are operated quite actively, we recommend using contact glue, such as the moment of plastic, BF-2, BF-4. They are applied with a thin layer on both parts of the product, connected, left for 5 minutes, after which they are pressed to each other. The stronger the pressure, the better provide gluing.
How to glue plastic with plastic, wood, glass and metal? In this case, it is necessary to more carefully treat the choice of glue. In order to combine plastic with metal, it is best to use epoxy, also polyurethane compounds.
That is, those that are sold in the kit for two bottles. They must be mixed with each other, that is, hardener and glue itself. The plastic with wood, as well as the glass UXU Twist glue, glues very well. As for the connection of plastic with metals and wood, rubber, glue based on cyanoacrylate, that is, the well -known superclles, is best coped.

As you can see, when using the right adhesive compounds, you can easily repair the parts of the car, children's toys, as well as household appliances.
