Powder coating is a solid powder synthetic resin coating composed of solid resin, pigments, fillers and additives.
Different from common solvent-based coatings and water-based coatings, its dispersing medium is not solvent and water, but air.
It has no solvent pollution, 100% film formation, low energy consumption. Powder coatings are thermoplastic and thermosetting two categories.
The coating appearance (gloss and leveling) of thermoplastic powder coating is poor, and the adhesion between the metal is also poor, so it is rarely used in the field of automobiles, television, refrigerators, washing machines and other coating.
These metal coating commonly uses thermosetting powder coating, thermosetting powder coating is thermosetting synthetic resin for film material, in the drying process of resin melting first, after chemical crosslinking curing into smooth and hard film.
The appearance, mechanical properties and corrosion resistance of the film can meet the requirements of metal coating.
Powder coating powder manufacturer coatings have fire resistance, corrosion resistance, high temperature resistance, do not fade and do not fall off, all aspects are better than liquid coatings.
