Powder Coating

Powder coating is a type of coating that is applied as a dry powder and then cured under heat to form a hard, durable finish. It is commonly used as a protective and decorative coating for a wide range of products, including metal furniture, automotive parts, appliances, and industrial equipment.

Unlike traditional liquid paint, powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension. Instead, the powder coating is typically made up of a mixture of finely ground particles of pigment and resin, which are electrostatically charged and sprayed onto the surface to be coated.

Once applied, the coated object is then heated in an oven, causing the powder particles to melt and flow together, forming a smooth and even coating. The heat also triggers a chemical reaction that cross-links the polymer molecules, creating a strong and durable finish.

Powder coating offers several advantages over traditional liquid paint. It provides a thicker and more uniform coating, with excellent resistance to chipping, scratching, and fading. It also has a lower environmental impact, as it produces less waste and contains no volatile organic compounds (VOCs).

In the supply class "Paints, Dopes, Varnishes, And Related Products" and the supply group "Brushes, Paints, Sealers, And Adhesives," powder coating would fall under the category of paints. It is a specialized type of paint that is applied in powder form and then cured to create a durable finish.
