摘要
A radiation-curable release composition comprises:(a) from about 50 to about 100 parts by weight of an organopolysiloxane of the formula (I) wherein R is CH2=CH-C(O)-O-CH2-CH(OH)-CH2-O-CH2-CH2-CH2-, n is 5 to 15, and p is 50 to 150;(b) from 0 to about 50 parts by weight of one or more organopolysiloxanes comprising organopolysiloxanes selected from the group consisting of those of formulae (II) and (III) wherein R is CH2=CH-C(O)-O-CH2-CH(OH)-CH2-O-CH2-CH2-CH2-, m is 1 to 10, and q is 151 to 300; and wherein R is CH2=CH-C(O)-O-CH2-CH(OH)-CH2-O-CH2-CH2-CH2-, and r is 20 to 500;(c) from 0 to about 10 parts by weight of an organopolysiloxane of formula (IV) wherein R is CH2=CH-C(O)-O-CH2-CH(OH)-CH2-O-CH2-CH2-CH2-, s is 1 to 10, and t is 301 to 1000;(d) from 0 to about 10 parts by weight of at least one additive for modifying the adhesion and flexibility properties of the composition, the at least one additive selected from the group consisting of acrylate and vinyl ether monomers; and(e) from 0 to about 10 parts by weight of a photoinitiator.For easier release, at least one of component (b) or (c) is preferably present in the composition.
