Powder coating is a colored plastic or polymer compound that is applied as a dry powder. The powder is applied using an electrostatic charge. This charge forces the powder into tight areas and corners and causes the powder to cling to the metal. It is then placed in a curing oven where the powder goes from a dry form to a gel coat and then flows out to a liquid. After baking for a set time, the item is removed and allowed to cool down to room temp. This creates a hard finish that is more abrasion resistant than conventional paint.
Powders come in a variety of colors and textures. There are over 6400 color and texture variations on the market. From standard single tone colors to two stage top coats, transparents. veins, rivers, and wrinkle textures.
The process of powder coating is similar to traditional liquid paint. The part goes through surface preparation of sandblasting and outgassing. Then the powder is applied before being placed in an oven for curing.
