Claim:
In a process for the coating of substrates with crosslinkable silicone(s) wherein an antimisting additive is employed for reducing the formation of aerosol, the improvement comprising adding to said crosslinkable silicone(s) at least one antimisting additive which is an alkenyl-functional siloxane copolymer comprising (a) siloxane units of the formula R a ⁢ Si ⁡ ( OR 1 ) ⁢ O 4 - ( a + b ) 2 b ( I ) where each R independently is an identical or different, optionally halogenated hydrocarbon radical having from 1 to 18 carbon atoms per radical, R 1 each is an identical or different alkyl radical having from 1 to 4 carbon atoms per radical, optionally substituted by an ether oxygen atom, a is 0, 1, 2 or 3, b is 0, 1, 2 or 3 and the sum a+b is not greater than 3, (b) per molecule at least one siloxane unit of the formula A ⁢ Si ⁢ R c ⁢ SiO 4 - ( c + 1 ) 2 ( II ) where c is 0, 1 or 2, A is a radical of the formula —CH 2 CHR 3 —R 2 (CR 3 ═CH 2 ) x-1 where R 2 is a divalent, trivalent or tetravalent hydrocarbon radical having from 1 to 25 carbon atoms per radical, R 3 is a hydrogen atom or an alkyl radical having from 1 to 6 carbon atoms per radical, and x is 2, 3 or 4, and (c) per molecule on average at least one unit selected from the group consisting of units of the formulae where A 1 is a radical of the formula where A 2 is a radical of the formula with the proviso that R 2 is not a divalent hydrocarbon radical, and A 3 is a radical of the formula with the proviso that R 2 is not a divalent or trivalent hydrocarbon radical.
