Powder Coating Facts
The parts to be coated are electrically grounded so the charged particles adhere to them until melted and fused into a solid coating in a curing oven.
Attributes of powder coating:
Unlike liquid paint, no solvents are used, so only negligible amounts of VOCs, if any, are released into the air.
Unused or oversprayed powder can be recovered, so any waste is minimal and can be disposed of easily and safely.
The powder coating process is environmentally friendly and virtually pollution-free.
Thousands of different kinds of parts and products are now powder coated.
Powder coating gives consumers, businesses, and industry one of the most economical, longest-lasting, and most color-durable quality finishes available.
Color selection is virtually unlimited with high and low gloss, metallic, and clear finishes available. And colors stay bright and vibrant longer. Texture selections range from smooth surfaces to a wrinkled or matte finish, and rough textures designed for hiding surface imperfections.
Protects the Environment
While liquid finishes contain solvents which have pollutants known as volatile organic compounds (VOCs), powder coating contains no solvents and releases negligible amounts, if any, of VOCs into the atmosphere. Thus, there is no longer a need for finishers to buy costly pollution control equipment. In addition, most powder coating overspray that does not adhere to the part can be retrieved and reused, virtually eliminating the waste commonly found in liquid finishing processes.
Elimination of VOCs and reduction of wastes saves money and helps companies comply more easily and economically with the regulations of the U.S. Environmental Protection Agency.
