Powder Coating

Powder coating is a new 100% solids solvent-free powdered paint. With a solvent-free, non-polluting, recyclable, environmentally friendly, saving energy and resources, reduce labor intensity and film mechanical strength. 

Powder coatings are completely different with the general form of the coating, which is present in the fine powder state. Since no solvent is used, so called powder coating. The main characteristics of the powder coatings are: a sound, a high efficiency and saving of resources and environmental characteristics. 

It has two categories: thermoplastic powder coatings and thermoset powder coatings. 
The thermoplastic powder coating is made of a thermoplastic resin, pigment, fillers, plasticizers and stabilizers component composition. The thermoplastic powder coating comprising: polyethylene, polypropylene, polyester, polyvinyl chloride, chlorinated polyether, a polyamide, cellulose-based, polyester-based. 

The thermosetting powder coating is a thermosetting resin, a curing agent, pigments, fillers and additives and other components. A thermosetting powder paint comprising: an epoxy resin, a polyester, an acrylic resin-based. 

Powder coating, mixed with a certain proportion by special resins, fillers, curing agents and other additives, and then prepared by hot extrusion and crushing screening and other processes from. They are at room temperature, storage stability, by electrostatic spraying, frictional coating (thermosetting method) or fluidized bed dipping (thermoplastic method), and then heating and baking melted and solidified, so that the formation of smooth and bright permanent coating, to achieve decorative and anti-corrosion purposes.
