To provide the aluminum with a decorative and protective layer, a powder coating can be chosen.
After a number of pre-treatments, including degreasing and rinsing, the powder coating is applied by means of an electrostatic process. The negatively charged powder is applied to the aluminum object, which is positively charged. The subsequent electrostatic effect creates a temporary adhesion of the coating. The object is then heated in an oven so that the coating melts (the so-called baking process), after which the coating is given a chance to cure.
Once cured, a solid bond is formed between the coating and the aluminum.
