powder coating

a coating created by applying dry paint in the form of a fine powder

Powder coating is a finishing process used to apply a protective and decorative layer to metal surfaces. It involves applying a dry, powdery paint that is then heated in an oven to melt and blend into a smooth, hard finish. This method creates a durable, scratch-resistant, and rust-resistant coating that is often used on items like car parts, household devices, and outdoor furniture.
