Abstract:
A curable silicone-based coating composition curable to a flexible coating at a coat weight of up to 15 g/m2 when cured comprising:A. an organopolysiloxane polymer having a siloxane backbone of degree of polymerization no more than 150 end-blocked with at least two silicon-bonded groups R, wherein R denotes an olefinically unsaturated hydrocarbon substituent, an alkoxy group or a hydroxyl group; B. a cross-linking organosilicon material having at least 3 silicon-bonded reactive groups; C. a catalyst capable of promoting the reaction between the silicon-bonded groups R of compound A and the silicon-bonded reactive group of compound B; D. optionally a non-reinforcing filler; and E. optionally up to a maximum of 3% by weight of a reinforcing filler; wherein organopolysiloxane (A) is a polymer containing vinylmethylsiloxane units in which 10 to 50 mole % of the siloxane units are vinylmethylsiloxane units.
