What is Powder Coating?
Since its introduction in North America almost 40 years ago, powder coating has become the fastest growing finishing technology, currently representing over 10 percent of the total industrial finishing market. More and more finishing engineers for a countless array of products have switched from liquid finishing to powder coating as way to produce a high quality and durable finish while maximizing production, cutting costs, improving efficiency, and complying with increasingly stingent environmental regulations.
How Powder Coating Works
Powder coating is a dry finishing process, using finely ground particles of pigment and resin which are electronically charged and sprayed onto a part to be coated. The coating process can be done manually or automatically with a wide variety of equipment available. The parts to be coated are electrically grounded so that the charged powder particles projected at them adhere to the parts 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.
