Powder coating is the technique of applying dry paint to a part in the form of a fine powder which is electrically charged. The part is electrically 'earthed' so the powder is attracted to the part and stays in place through static electricity. The part is then placed in an oven and is subject to temperature which melts the polyester and allows the finish to flow and cure before the part is cooled and ready to use.
