Powder Coat
Powder coating is one of the newest, most-durable finishes available. The powder is a mixture of finely ground particles of pigment and resin, which is sprayed onto a surface. The charged particles adhere to the electronically grounded surface. Then they are heated into a smooth coating in a curing oven. The result is an attractive, durable, high-quality finish. Powder coat finishes are more resistant to chipping, scratching, UV damage, and rust. Powder coating is one of the most environmentally-friendly finishes because it does not contain solvents and releases negligible amounts, if any, of volatile organic compounds (VOCs) into the atmosphere.
The coating material is finely ground into a granulated, dry solid powder. It is then applied electrostatically to a surface (typically metal). The static charge provides an adhesive force for the dry particles. The application of heat causes the particles to melt. The individual particles fuse together to form a continuous fluid layer. Finally, additional heat initiates a chemical cure reaction which forms a solid paint film.
Colors, are designated using the RAL Design System, Classic K7 color chart These colors are defined by a seven digit color code indicating Hue,Lightness and Chroma of each color. The RAL system follows an internationally used color measurement system laid down in 1976.
