Powder coating is a finishing process where a dry, powdered paint is applied to a surface and then cured under heat to form a durable, protective layer. The powder is electrostatically charged and sprayed onto the object, creating an even coating that adheres without the need for solvents. After application, the coated item is baked in an oven, which causes the powder to melt and bond to the surface, resulting in a smooth, tough finish resistant to chipping, fading, and corrosion.
