OVERVIEW

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 or with ultraviolet light. 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 metals, such as household appliances, aluminium extrusions, drum hardware, automobiles, and bicycle frames.
 

Epoxies

Epoxies were the first widely used powders. They are very durable, offer excellent hardness and have arguably the best chemical and corrosion resistance of all available powders. Another plus of this type of powder is its ease of use and a wide range of cure schedules.
Epoxies adhere to metals extremely well, with various pretreatments of the metal providing excellent adhesion, including phosphate coating and sandblasting.
