Powder Coating Facts

What is powder coating?

Powder coating is a type of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a "skin". 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, aluminum extrusions, drum hardware, and automobile, motorcycle and bicycle parts.

Powder coating is a combination of pigment and resin that is ground into a powder form and is sprayed on an item to be coated. The powder is charged with high voltage which is then attracted to the electrically grounded item to be coated. The item is heated in a curing oven until the powder flows into a liquid form. After curing for a specific amount of time, the part is removed to cool, leaving a high quality, durable finish.

What is a two coat powder coating system?

By combining a base coat with a top coat, incredible custom powder coat colors can be created. Not only are unique, personalized colors created, but the durability, impact, scratch and wear resistance of the coating is enhanced with a two coat application as well.
