Powder coating is a finishing process that applies a dry powder to surfaces, typically metals, to create a durable and protective layer. The powder is made from a mixture of resin and pigment, which is electrostatically charged and sprayed onto the surface. Once applied, the coated item is heated in an oven, causing the powder to melt and form a smooth, even finish. This method is popular for its ability to resist chipping, scratching, and fading, making it ideal for various applications, including automotive parts, furniture, and appliances. Additionally, powder coating is more environmentally friendly than traditional liquid paints, as it produces fewer volatile organic compounds (VOCs).
