The primer effect of nylon plastic spray paint nylon treatment agent

Plastics have become an important way of modern industrial material applications due to changes in mechanical and physical properties. The same is true for our commonly used nylon plastics , which are modified by adding glass fiber or calcium titanate to the nylon substrate. That how to evaluate the modified nylon material in the field of painting the surface paint of energy?

The modified nylon plastic has excellent mechanical properties, good heat resistance, dimensional stability and abrasion resistance, and has good characteristics in injection molding , appearance, and coloring. However, the general surface spray treatment process of glass fiber nylon is relatively common. The surface tension of glass fiber nylon plastic is low, and the adhesion effect after the material structure is complex is relatively poor. The adhesion of the paint directly after spraying is poor, which causes the paint The adhesion is poor and the paint will be peeled off, and the degree of seriousness is even no adhesion.

According to the experience of the coating industry and the principle of coating adhesion, to prevent the phenomenon of paint falling off in the glass fiber nylon plastic spray paint, it is necessary to improve the adhesion of the coating on the nylon substrate. Adding glass fiber nylon treatment agent is to cover the surface of modified nylon plastic in the form of primer, which assists in strengthening the firm connection between the paint and the substrate to achieve a firm coating. It has a variety of principles such as intermolecular force and mechanical bonding force. Compared with other methods such as flame and corona treatment, it has the advantages of stability, convenient construction, strong adhesion and high efficiency.

The application of glass fiber nylon treatment agent covers the spraying of plastic shells, tablet computer shells, electronic products, toys, household appliances and other different industries in different fields. Therefore, in the applicable spraying method, either a hand spray line or an automatic line can be used. When testing the use environment, it can pass different bonding strength tests such as 100 grid, knife cutting, high and low temperature, so as to solve the problem of poor paint adhesion and paint drop.
