Curable epoxy groups containing organopolysiloxanes, process for their preparation and their use as curable abhesive coating agents.

摘要

Organopolysiloxanes are disclosed which contain, aside from methyl groups, alkyl groups with 1 to 20 carbon atoms, aryl groups or aralkyl groups, epoxy groups which are linked over Si-C bonds to silicon atoms of the polysiloxanes, and R3OH groups, R3 being a divalent alkylene groups with 3 to 11 carbon atoms. The organopolysiloxanes have good compatibility with photoinitiators and adhesion and release properties which can be adjusted for the intended application by coordinating the long chain alkyl groups, the epoxy groups and the -R3OH groups.
