Description

Powder coating involves applying a finely ground resin (powder) to a substrate and subjecting this powder to heat. During the heating process, the powder melts and creates a uniform, continuous coating. Powder coatings provide excellent corrosion, impact, and abrasion resistance, as well as gloss retention. Manufacturers employ powder coating processes in a wide variety of applications as they are versatile and present savings in labor, materials, and energy costs, and because powder coats are durable. Powder-coating processes are employed in many production settings involving protective finishes. Powder formulations can be created to deliver cosmetic, protective, and longevity characteristics, and to achieve maximum hardness, chemical resistance, and gloss retention. Although equipment and materials costs are similar in powder-coating and liquid-coating processes, powder-coating processes provide a number of advantages over other surface-coating methods.
