Powder coating is a dry finishing process which uses electrostatic spray deposition principle. Powder paint particles are charged using an electrostatic spray gun and sprayed on to the grounded parts. The powder coated parts are then cured in a hot air circulating oven to produce long molecular chains, resulting in high cross-link density coating. Powder coatings are generally harder and offer improved impact, abrasion, chemical resistance, and superior exterior weatherability over most liquid coatings.
