Patent ID: 7238755

Claim:
A process for reducing the formation of an aerosol during the application of a crosslinkable silicone coating composition, the improvement comprising adding to said crosslinkable silicone coating composition at least one antimisting additive comprising a liquid, branched siloxane polymer containing alkenyl groups prepared by reacting α,ω-dialkenylsiloxane polymers (1) of the formula R 1 x R 3-x SiO(R 2 Si—R 2 —SiR 2 O) m (R 2 SiO) n SiR 3-x R 1 x (I) where R denotes identical or different, unhalogenated or halogenated hydrocarbon radicals having from 1 to 18 carbon atoms per radical, R 1 is a terminally aliphatically unsaturated organic radical, R 2 is a divalent organic radical having 2 to 30 carbon atoms per radical or a divalent silane or siloxane radical having 2 to 10 Si units, x is identical or different and is 0 or 1, on average from 0.7 to 1.0, m is 0 or an integer from 1 to 10, and n is 0 or an integer from 1 to 1000, with organosilicon compound(s) (2) containing at least 3 Si-bonded hydrogen atoms per molecule and of the formula where R is as defined above, R 3 is a trivalent to decavalent aliphatically saturated hydrocarbon radical having 1 to 20 carbon atoms, which optionally contains one or more heteroatoms selected from the group of oxygen, boron, silicon and titanium, R 4 is a hydrogen atom or an alkyl radical having from 1 to 6 carbon atoms per radical, R 5 is a divalent hydrocarbon radical having from 2 to 30 carbon atoms, which can be linear, branched or cyclic and optionally contains one or more non-adjacent oxygen atoms, a is 0, 1, 2 or 3, b is 0, 1 or 2, c is 0 or 1, d is 0, 1 or 2, z is an integer from 3 to 10, e, f, g, k and 1 are each 0 or a positive integer, with the proviso that when 1 is a positive integer, the structural elements VII are bonded to the structural elements VI, in the presence of catalysts (3) which promote the addition of Si-bonded hydrogen onto aliphatic double bond.
