Only minimum surface is available for gluing polycarbonate coverings on half shell cases in the manufacture of mobile telephones. Modern UV adhesives are used – one-component resins that harden in seconds when exposed to UV light through the transparent covering, which ensures very good electrical insulation.
These small surfaces must be extremely well prepared to achieve improved adhesion. Openair® plasma activation results in an exceptionally effective joining of advanced materials and combinations with a variety of plastics.
