The invention relates to a composition based on crosslinkable epoxy-functional organopolysiloxanes. This composition comprises: A. at least 10% by weight of a linear polyorganosiloxane A (POS) of average general formula (II): <IMAGE> (II) in which: R1 is CH3, R' is an alkylene containing 2 to 50 C, R is an alkyl having from 6 to 26 C, X is R1, H, -R'-epoxy or hydroxyl, x=40-150, t=3-9, z=0-5 and y=0, B. at least one second crosslinkable epoxy-functional POS (B), B being present in the proportion of at most 90% by weight and corresponding to: B(a) with x=160-1000, t=1-15, z=0-5 and y=0, B(b) with x=0-120, t=10-30, z=0-5 and y=0, or B(c) with x=0-200, t=0-5, z=0-5 and y=10-90, C. and at least one photoinitiator. This composition can be used in the manufacture of protectors for adhesive bodies ("release liners"), papers or plastics or of liner-free self-adhesive labels. |
