Its purpose is to cover (an object) with a polyester or epoxy powder, which is then heated to fuse into a protective layer. It’s used to re-cover such things as rims for vehicles, grills for vehicles, lawn furniture, lawn mowers, tool boxes, and much more. It not only dresses up your object but coats it with an added layer of protection from wear and tear and strain form the environment. Powder coating is also very environmentally friendly as it produces no VOC’s.
