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, the ratio of the number of silicon-bonded hydrogen atoms of (ii) to the number of silicon-bonded alkenyl groups of (i) is from 0.5:1 to 4.5:1, (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 (mPaÂ·s) (1 millipascal-second=1 centipoise) obtained by a method comprising mixing: (a) at least one organohydrogensilicon compound containing at least two silicon-bonded hydrogen groups per molecule; (b) at least one organoalkenylsiloxane containing at least three silicon-bonded alkenyl groups per molecule, and (c) a platinum group metal-containing catalyst which is present in an amount sufficient to provide 1 to 250 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 silicon-bonded alkenyl groups of Component (b) is less than or equal to 1:4.6.
