Powder coating is the process of coating a surface in which a powder material is applied using an electrostatic or compressed air method, or sometimes a fluidized bed.
The applied powder is then heated (cured) in an oven to its melting point, after which it flows to form a smooth film which dries to a firm, durable finish very resistent to scratches, cracking, peeling, UV rays and rust.
Because of the advanced method with which powder coatings are applied, all types of powder coating provide a durable, uniform and attractive finish. All powder coatings are decorative and protective, and different formulations of powder coatings are available to provide extra protection from ultra-violet rays, corrosion, abrasion, and chemicals. Some types are even approved for use by the FDA in food grade applications.
What's more, they provide good electrical insulation properties and can also have special characteristics like electrostatic discharge.
