Plasma pretreatment of car exterior parts – cleaning and activation of complex multi-materials
Car
exterior parts are today made of complex combinations of materials
ranging
from metal tailored blanks to sheet molded compounds (SMC) and glass
fiber reinforced plastics (GFRP) to hybrid plastics.The
starting materials have very different surface qualities.
Plasma
pretreatment is a key technology for achieving stable material
combinations and high-quality surface finishes with
secure adhesion.
It
points the way ahead, both economically and ecologically.

- Surface activation prior to painting of bumpers made of PP/EPDM compounds
- Openair® Plasma pre-paint surface pretreatment of fenders made of SMC.
- Plasma microfine cleaning of ceramic coatings prior to glazing.
- Plasma microfine cleaning of aluminum frames for waterproof bonding of glass sunroofs

The future of the automobile – new material combinations with light-weight construction and plasma coating
Conventional sheet metal construction in automobile manufacturing is being replaced by new, lightweight techniques. Significant resources will be saved as a result. With plasma coating, new composite materials can be reliably bonded – even without solvent-based primers
