Powder coating – a painting process in which colored dry powder paint is used. The dry powder is provided a negative electrostatic charge (from 10,000 to 90,000 volts). Sometimes referred to as powder painting and dry painting. After the object is covered with paint – it goes into the oven where the paint melts evenly coating the surface. In the oven chemical compounds react with each other and polymerise improving paint quality characteristics. Powder coated surfaces are characterized by hardness, color, attractiveness, durability, high quality, scratch resistance and environmental impact. Wet paint requires a solvent and powder coating does not. This provides a firmer surface layer and protects better the surface from the environment.
Powder paint is usually made of polyester, polyurethane, polyester, epoxy resin and acrylic.
