What is Powder Coating?
Powder coating is an advanced method of applying a decorative and protective finish to a wide range of materials and products that are used by both industries and consumers. The powder used for the process is a mixture of finely ground particles of pigment and resin, which is sprayed onto a surface to be coated. The powder is most commonly applied by spraying with a gun that electrostatically charges the powder as it exits the tip. In most cases, the powder is applied directly to a clean, bare metal surface, with no primer or base coat (powder coating can also be applied to glass, ceramics, temperature resistant plastics and even wood). The part that is being coated is electrically grounded, causing the charged powder to cling to it. After coating, the part with the loose powder clinging to it is placed in an oven to cure. In the curing process, the powder melts and flows over the surface of the object without drips, runs or sags. The result is a highly durable and attractive finish in a wide variety of colors, glosses and textures. Powder coating is the fastest-growing finishing technology in North America, representing over 10% of all industrial finishing applications.
Brake drums were glass bead blasted to remove rust and scale. They were then cleaned and a 1.5-3 mil coating of powder was applied and cured.
Superior Durability to Most Liquid Paints
Powder coating gives consumers, businesses, and industry one of the most economical, longest-lasting, and most color-durable quality finishes available. Powder coated surfaces are more resistant to chipping, scratching, fading, and wearing than other finishes. Color selection is virtually unlimited with high and low gloss, metallic, and clear finishes available. And colors stay bright and vibrant longer. Texture selections range from smooth surfaces to a wrinkled or matte finish, and rough textures designed for hiding surface imperfections.
