Manufacturing process of powder coating

Coatings are prepared by mixing special resins, pigments and fillers, curing agents and other additives in a certain proportion, and then through hot extrusion, crushing and sieving. They are stable in storage at room temperature. After electrostatic spraying, friction spraying (thermosetting method) or fluidized bed dipping (thermoplastic method), they are heated and baked to melt and solidify to form a flat and bright permanent coating film to achieve decorative properties. and anti-corrosion purposes.
