Powder coating is a dry finishing process, using finely ground particles of pigment and resin which are electrostatically charged and sprayed onto a part to be coated. The parts to be coated are electrostatically grounded so that the charged powder particles projected at them adhere and are held there until melted and fused into a smooth coating in the curing oven. The result is a uniform, durable, high quality finish that is also environmentally friendly. The performance characteristics of powder coating match or exceed the characteristics achieved from conventional solvent based coatings. Powder coating provides an extremely durable finish and has bonding capabilities superior to traditional wet paint. In addition it has excellent chemical resistance.
