Powder coating works by applying dry colour powder to a metal surface, before ‘baking’ the colour onto the surface using heat to form a hard finish. The colour powder is applied electrostatically using a power gun. This means that it is sprayed on using compressed air, passing over an electrode in the gun.
It is used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals, such as household appliances, aluminium extrusions, drum hardware, automobiles, and bicycle frames.
