[0002] Powder coating is a solid powder coating, the main components of which are resin, pigment, filler and auxiliary agent. The particles of powder coating are in powder form and do not contain solvents. Compared with traditional liquid coatings, it has the advantages of environmental protection and high efficiency. The dispersion medium of powder coating is air, which has the characteristics of no solvent pollution, 100% film formation and low energy consumption. Powder coating is a kind of coating that can effectively save energy and has environmental protection effects, and is becoming widely popular.
