Powercoating is a method of coloring that uses dry powder. The powder is electrostatically charged in a special gun. Just like a comb charged by being run through your hair can pick up small pieces of paper, charged powdercoating sticks to metal. Once the sticky powder is applied the metal part is run through an oven, which causes the powder to set into a paint-like coating that is tougher than paint.
Kernel uses 4 mil thick layers of powdercoat on all of our products. From this thick layer, our shelves benefit in luster, durability, and color quality. There are many good reasons that the auto industry uses powdercoating exclusively and we agree with all of them.
