PROCESS FOR PRETREATING THE SURFACES OF PLASTIC COMPONENTS AND PLASTIC COMPONENT PRETREATED BY THIS PROCESS

摘要

In order to improve the adhesion of coatings, especially metal coatings, to the surfaces of plastic components, the latter are pretreated in low-pressure plasma with a process gas containing sulphur hexafluoride (SF6) which is substantially free of oxygen, the plastic surfaces being kept free of fluorine deposits or inclusions during the pretreatment.
