What is best to glue plastic

Plastic - material, created on the basis of different polymers. Therefore, the market can be found mixed with different adhesive composition. There are both universal and special types of adhesives. When connecting parts made of plastic can use a variety of methods.

Choose a suitable adhesive

When selecting an adhesive, consider the use of foreign plastic compositions is highly undesirable. In addition, many plastics contain a variety of excipients that have a negative impact on strength. Sometimes in the production of plastic parts molding is used. The result of this treatment, the surface is very smooth. It requires careful preparation prior to bonding.

Study the label, which is usually applied to the inner surface of the plastic parts. For example, PUR - PUR, and PP - polypropylene, ABS, PVC, phenol and fiberglass. It is usually applied to the inner parts. Among the most popular adhesives is suitable for various kinds of plastics include: Time, Strong Plast, UNU, Welcon constraction, AKEIX. Universal compounds can be used if you do not understand the different types of plastic. But for gluing polyurethane, vinyl, fiberglass and phenol is better to use two kinds of adhesives, such as, Welcon constraction. The adhesive is suitable for use both indoors and outdoors.

Choose a suitable method

To improve the quality of gluing some types of plastic will help heating method. It is suitable for thermosetting polymers or polyurethanes. Connection softened elements will provide bonding strength. Sometimes used solutions of various polymers. They contribute to the homogeneity of the adhesive joint. The maximum strong connection of polyurethane and polypropylene can be achieved using epoxy glue.

For qualitative connection of two plastic parts you should keep them for some time under pressure. Even for bond used a method of reinforcement. For example, on a heated plastic surface a layer of metallic powder cast - iron or steel filings, which are dissolved in an organic solvent or connect with plastic heating method. Choose a solvent in accordance with the type of plastic. For example, suitable polystyrene toluene.

You can find special adhesive tapes, which are used even on an unprepared surface. Specially designed plastic double-sided adhesive tape will help to quickly glue plastic. These tapes allow you to connect not only a uniform surface, and plastic and glass, metal, wood.
