Dry powder is pneumatically fed from a supply reservoir to a spray gun where a low amperage, high voltage charge is imparted to the powder particles. The powder used in the powder coating process is comprised of resins and pigments and in its dry, formulated state is then sprayed onto a part to be finished. The parts to be coated are electrically grounded so that the charged particles projected at them are firmly attracted to the part's surfaces and held there until melted and fused into a smooth coating in the baking ovens.

Powder coatings are used on an increasing variety of products and components. Industries with multiple applications include appliance, automotive, electrical, medical and office furniture, building and architectural, farm, garden and industrial machinery, fabricated products and miscellaneous products.
