Surface treatment

Before metal surfaces can be painted or powder-coated, they must be pre-treated. It is often through phosphatation that metal surfaces obtain the durable base that then enables the subsequent application of paint, lacquer or other coatings. The main areas of application are short-term corrosion protection and surface preparation for lacquering and powder coating, as a primer for abrasion- and friction-reduction additives and wettability control. Phosphatation is also used, for example, in electrical insulation, chemical polishing of cover caps on high-quality bottles, and electric polishing on vehicle headlamps i. The most well-known procedures are zinc and iron phosphatation.
