Abstract:
A silicone coating composition comprising:(A) a solventless silicone coating composition selected from compositions comprising (Aâ€²)(i) an organosilicon compound containing at least two silicon-bonded alkenyl groups per molecule, (ii) an organohydrogensilicon compound containing at least two silicon-bonded hydrogen atoms per molecule, (iii) a platinum group metal-containing catalyst, and (iv) an inhibitor, or (Aâ€³)(I) an organosilicon compound having at least two groups selected from the group consisting of epoxy groups, vinyl ether groups, acrylamide groups, and acrylate groups; and (II) an initiator; and (B) a liquid silicone mist suppressant composition having a viscosity of from 150 to 50,000 millipascal-seconds (mPa.s) (1 millipascal-second=1 centipoise) obtained by a method comprising mixing: (a) at least one organohydrogensilicon compound containing at least three silicon-bonded hydrogen groups per molecule; (b) at least one compound containing at least two alkenyl groups per molecule; and (c) a platinum group metal-containing catalyst which is present in an amount sufficient to provide 0.1 to 10 weight parts of platinum group metal per million weight parts of (a)+(b), with the proviso that the ratio of the number of silicon-bonded hydrogen atoms of Component (a) to the number of alkenyl groups of Component (b) is at least 4.6:1.
