Powder Coating is a method of applying a protective or decorative finish onto a manufactured product. Powder coating materials are finely ground particles of pigments resins, binders, fillers and hardens.

Powder coatings that are applied for decorative purposes use electrostatic spray application equipment. Spray application uses a delivery system to bring powder to spray gun and a charging system to impart electrostatic charges, in most current corona charging systems for electrostatic application. As the powder passes through the electrostatic field, it picks up a charge and is attracted to a ground substrate. The electrostatic spray application system required a pre treatment method to prepare the part surface for coating, an application system to apply the powder, a booth with recovery system to contain the process and a curing oven to cross link the material and conveyor.
