[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives. Unlike ordinary solvent-based coatings and water-based coatings, its dispersion medium is air instead of solvent and water. It has the characteristics of no solvent pollution, 100% film formation and low energy consumption. Powder coatings are divided into two categories: thermoplastic and thermosetting. In the production of powder coatings, the raw materials must first be crushed, and then the crushed raw materials must be pre-mixed, melt-extruded, tableted, crushed, finely powdered, graded and sieved, and the finished products must be packaged.
