The whole can be divided into two categories: thermosetting and thermoplastic. Moreover, after the low molecular weight prepolymer is cured, It can form network cross-linked macromolecules, so the coating has better anti-corrosion and mechanical properties. Adding additives can improve the adhesion to metal.

Epoxy powder coatings are the first to be used in thermosetting powder coatings due to their excellent adhesion to metals, corrosion resistance, hardness, flexibility and impact strength. The chemical stability is second only to polytetrafluoroethylene. Epoxy polyester powder coating Epoxy polyester powder coating is a powder coating made of epoxy resin and polyester resin as the main raw material.

Polyvinyl chloride powder coating. It can prevent food contamination and has high insulation strength for electrostatic spraying. However,electrostatic powder coating paint there are some shortcomings, such as high melting temperature, low coloring level, and poor adhesion to metal surfaces. The contribution of these several components to the performance of the formed powder coating is mutually restricted and affects each other.

These characteristics make thermoplastic powder coatings occupy a large proportion of the coatings market. Acrylic powder coating Acrylic resin powder coating has two types: thermoplastic and thermosetting. It is not easy to turn yellow during the baking process, has high gloss, good leveling, full paint film, and light color.

Polyethylene powder paint coating has excellent corrosion resistance, chemical resistance and excellent electrical insulation and ultraviolet radiation resistance.The disadvantage is that it has poor adhesion to metal. The coating film has good corrosion resistance and anti-dissolution performance against a variety of acids, alkalis and solvents.
