Powder Coating

Powder coating is the electrostatic application of organic powder to metal parts requiring protective or decorative coating. The powder is cured by heating or baking, resulting in a hard, continuous coating.

The powder coat process includes pre-treatment, powder application and high-temperature powder curing. The process begins with pre-treatment/surface preparation of the substrate. Each part is cleaned, removing grease, dirt and anything else that might interfere with the painting process.

This may include abrasive/mechanical or chemical cleaning, though it usually consists simply of cleaning the metal surface and pre-treating it in some fashion (e.g. phosphating) to prepare the surface to bond well with the powder during the curing process that follows as well as providing a degree of corrosion resistance. Without proper pre-treatment, the powder on a part will chip and corrode easily.
