Plastics tend to acquire an electrostatic charge fast and thus attract dust. Even minor contaminations cause rejects. Cleaning and pretreatment of the components is a fundamental prerequisite for good wetting and paint adhesion and thus decisive for the successful coating of plastic components.
Well-established is cleaning by using wet chemical methods. Parts with a normal degree of soiling are cleaned by means of alkaline spray degreasing and then rinsed with DI water. More heavily soiled parts are degreased in two stages at higher temperatures and using higher spray pressures.
