Difference Between Painting and Coating
Liquid painting and powder coating are two techniques used in industrial finishing. Both typically require a heat curing process, but they differ greatly in their methods of application. Liquid painting is the standard method employed for coating. With recent changes in finishing technology, powder coating is the latest popular option used for different substrates and powder coating provides better performance than painting—it is more resistant to chipping, scratching, and other wear because of the thermal bonding it undergoes during curing, and because it can be applied in much thicker layers.
Process
Painting involves the spreading of liquid paint over the product surface. It consists of a single component that dries when exposed to air or UV light. The powder coating process uses dry, free flowing powder. A spray gun spreads the powder electrostatically on the surface. It's then exposed to high temperature, which bakes the surface and melts the powder to create a smooth, solid layer.
