Powder coating is the process of applying protective coatings to surfaces by applying dry, electrostastically charged powders of typically thermoset or thermoplastic polymer onto a grounded surface using a specialized spray gun, forming a thin and even coat. Once applied, the coated surface is heated and/or cured to fuse the powder into a durable finish. Powder coating protects metals surfaces from corrosion, scratches, and other types of damage, and also provides a vibrant color finish.
