Powder coating is a dry finishing process that applies a protective and decorative layer to metal surfaces. Unlike traditional liquid paint, which relies on solvents to carry the pigment, powder coating uses finely ground particles of pigment and resin. These particles are electrically charged and are sprayed onto the grounded metal surface. Once applied, the coated object is subjected to heat in an oven, where the powder melts, flows, and cures to form a hard, durable finish.

This technique is widely used across various industries, including automotive, architectural, furniture, and appliances, due to its numerous advantages over conventional painting methods.
