RADIATION CURING ORGANOPOLYSILOXANE COMPOSITION

摘要

PURPOSE:The titled composition, obtained by incorporating a mercaptoalkyl group-containing organopolysiloxane with a photosensitizer, and rapidly curable to form films having improved film characteristics such as hydrophilic and antistatic properties. CONSTITUTION:A radiation curing organopolysiloxane composition obtained by incorporating (A) 100pts.wt. organopolysiloxane having at least one siloxane units expressed by formula I (R<1> is H or methyl; R<2> is monofunctional hydrocarbon; X is alkylene or -CO.O-; n is a positive number <=4; p is a positive number; m is 0 or a positive integer; a is 0, 1 or 2) in the molecule with (B) 0.1-50pts.wt. mercaptoalkyl group-containing organopolysiloxane having at least two siloxane units expressed by formula II (R<3> is alkylene; R<4> is monofunctional hydrocarbon; b is 0, 1 or 2) in the molecule and (C) 0-10pts.wt. photosensitizer.
