Powder coating is a surface treatment technique where parts made from aluminum or hot dip galvanized steel are coated with a powder of polyester or epoxy.
After a special chemical pretreatment of the material's surface, the coating is applied using powder sprayers. Electrostatic self-charge distributes it on the material's surface. Afterwards the powder is baked in an oven at a material’s temperature of approx. 180°C and runs into a coating.
