Varieties of glue and plastic

Plastic is a complex material; it is an organic material based on polymers. Bonding plastic will require more effort than with wood or leather. The reason for this is the chemical composition, surface structure and properties of plastics.

Important! This material has no pores, polymers are distinguished by low chemical activity and low adhesion.

In construction, glue for plastic is not used; welding is used instead. However, in everyday life such a method is practically inaccessible, and inexpedient.

Let's consider the possible options, what can be the glue for plastic:

• Liquid. These mixtures contain water or a solvent. After the glue is applied to the surface, they evaporate and harden the glue composition.
• Contact. Using this glue, plastic of various types is fastened. Hardener may be added to it.
• Reactionary. The bonding process requires certain factors - the presence of water or ultraviolet radiation. Such glue can be one- and two-component.
• Hot melt adhesive. Before gluing, it must be heated.

When choosing glue for plastic, you must definitely pay attention to the material:

• Children's designers make ABS plastic - epoxy cement is suitable for it.
• Polystyrene is the basis for cheap toys and artificial glass, it glues well with polycement.
• More dense, hard plastic is glued using special glue for polypropylene or polyethylene. Conventional glue for plastic will be inconclusive.

How to glue plastic products?

Bonding surfaces is a process that requires preparation and a certain algorithm of actions.

1. Get rid of dust. You need to wash the item with the addition of soap, you can wipe it with isopropyl alcohol or a special cleaner.

Important! To keep the surface clean, you must try not to touch it with your bare hands.

2. We grind the glued surfaces. In order for the surface to become rougher and better stick together, it is treated with 120-200 sandpaper. You can use steel wool or sandpaper.
3. If necessary, mix the components of the glue. In this case, you must strictly follow the instructions on the packaging, as it is important that parts of the composition are added in a certain ratio.
4. Apply glue for plastic on both surfaces. In this case, you need to use a brush or needle for very thin surfaces.

Important! When using a cement solvent, both parts are first compressed, and then, using an applicator, the solvent is applied.

5. Surfaces are gently compressed. This is done to remove air bubbles. The glue should not flow, if this happened - it must be wiped off immediately.
6. The surfaces are fixed with a clamp, vise, adhesive tape or elastic.

Important! Some types of glue harden in minutes, while others will need a day.

Popular brands of glue for plastic

Glue for plastic is very popular, there are a lot of varieties of it. Consider the most popular brands.

Cosmofen CA 12, USA

Such glue is also available in a large convenient volume bottle. Use is very simple. Equally suitable for bonding both glossy and rough surfaces.

Important! If you do not close the cork, the dispenser dries quickly.

Hosch, Germany

Very effective two-component tool for all surfaces. However, efficiency drops if flux powder is not added.

Loctite 406

The glue comes in a convenient package, it is easy to apply. The composition quickly spreads over the surfaces. It glues parts well and end-to-end, and lap, regardless of whether the surface is glossy or rough. To break them requires a lot of effort.

Super Moment Maxi, Ireland

Glue has excellent bonding properties. Indications for a break are excellent, considerable efforts are required.

How to remove glue from plastic?

Using glue for plastic, you need to ensure that its excess does not fall on excess surfaces. If this happens, you need to make some efforts to clean:

1. If the adhesive did not have time to harden, it is washed with a sponge. Then the surface is treated with a degreasing agent.
2. Acetone or nail polish remover is used to remove dried superglue. A cotton swab is wetted, with it, the stained area is processed. The procedure is repeated after a quarter of an hour. In the same way, you can use to remove the glue moment or nitrocellulose glue.
3. To eliminate rubber glue, gasoline is used. The liquid is applied to the swab and the surface is treated.
4. To remove plant-based glue, a solution is used that contains water, ammonia and denatured alcohol. All of them are taken in equal shares.

Important! Kerosene, acetone, mineral spirits, gasoline or solvent 646 are often used to remove glue. All of these agents are aggressive, therefore they should be used with caution.
