Powder coating is a solid powdery synthetic resin coating composed of solid resin, pigments, fillers and additives.
Unlike ordinary solvent-based paints and water-based paints, its dispersion medium is not solvent and water, but air. 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. Thermoplastic powder coatings have poor film appearance (gloss and leveling) and poor adhesion to metals, so they are rarely used in the automotive coating field. Automotive coatings generally use thermosetting powder coatings, which are Thermosetting synthetic resin is used as the film-forming material. The resin is first melted during the drying process, and then chemically cross-linked to solidify into a flat and hard coating film.
