    • 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): ##STR1## in which: R.sub.1 is CH.sub.3, R' is an alkylene containing 2 to 50 C, R is an alkyl having from 6 to 26 C, X is R.sub.1, 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.
    • 本发明涉及一种基于交联性环氧官能的有机聚硅氧烷的组合物。 该组合物包含:A.至少10重量%的平均通式(II)的线性聚有机硅氧烷A(POS):其中:R 1是CH 3,R'是含有2至50个的亚烷基 C,R为6至26个碳原子的烷基,X为R1,H,-R'-环氧或羟基,x = 40-150,t = 3-9,z = 0-5,y = 0,B 至少一个第二可交联环氧官能POS(B),B以至多90重量%的比例存在,并且对应于:B(a),其中x = 160-1000,t = 1-15,z = 0-5和y = 0,B(b)其中x = 0-120,t = 10-30,z = 0-5和y = 0,或B(c),x = 0-200,t = 0 -5,z = 0-5和y = 10-90,C和至少一种光引发剂。 该组合物可用于制造用于粘合体(“脱模衬垫”),纸张或塑料或无衬垫的自粘标签的保护件。
