Powder Coating Process

Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied Electrostatically and then cured under heat.

The powder may be a thermoplastic or a thermoset polymer. It is usually 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, Automobile, Motorcycle, and Bicycle parts.

CED Process

A DC charge is applied to a metal component immersed in a bath comprising of oppositely charged paint particles.

The Paint particles deposit on the component to a point where the coating reaches the desired thickness and an even continuous film is formed over every surface, crevice and corner.

On attaining desired thickness, the film insulates, resulting in stopping of attraction between paint particle and the component, thus completing the process. Depending upon the end use, you can choose either protective, decorative or a combination Coating.
