Claim:
A method of controlling misting when coating flexible supports, comprising steps I) and II): I) preparing a liquid silicone composition X which is a precursor of a silicone coating and said composition X comprises: at least one polyorganosiloxane A crosslinkable by polyaddition, by dehydrocondensation, by polycondensation, cationically or free-radically, optionally at least one crosslinking organosilicon compound B, optionally at least one catalyst or photoinitiator C selected according to a reaction envisaged for said polyorganosiloxane A, optionally at least one adhesion modulator system K, and optionally at least one crosslinking inhibitor D; and (II) coating said liquid silicone composition X onto a flexible support by a roll coating device, wherein said liquid silicone composition X is admixed with an antimisting additive E wherein: said additive E is in a liquid form, optionally following dilution by a diluent Jâ€², a solvent Jâ€³, or in a constituent of said liquid silicone composition X, and said additive E is obtained 1) by reacting at least one compound selected from compounds a) to d): a) an organosilicon resin F (optionally diluted by a diluent Jâ€², a solvent Jâ€³, or in a constituent of said liquid silicone composition X) comprising in a structure thereof, at least two different siloxy units selected from those of formula: (R 1 ) 3 SiO 1/2 (M unit), (R 1 ) 2 SiO 2/2 (D unit), R 1 SiO 3/2 (T unit), and SiO 4/2 (Q unit), in which units: the radicals R 1 , which are identical or different, are selected from linear or branched C 1 to C 6 alkyl radicals, C 2 to C 4 alkenyl radicals, and 3,3,3-trifluoropropyl, with the following conditions: that at least one of these units is a T or Q unit, and that said organosilicon resin F comprises groups â‰¡SiOH and/or â‰¡SiOR 2 , the amount by weight of groups OH and/or OR 2 being from 0.2% to 10% by weight, with R 2 being a linear or branched C 1 to C 6 alkyl radical, b) an organosilicon compound N of formula: R 3 d SiX 4-d in which R 3 is a monovalent hydrocarbon group having 1 to 5 carbon atoms, X is a hydrolyzable group, and d has an average value â‰¦1; c) a partially hydrolyzed condensate L of said organosilicon compound N; d) a condensate M of said organosilicon resin F with said organosilicon compound N or said condensate L; with: e) at least one organosiloxane monomer, oligomer and/or polymer G which is: in which 1 â‰¦f â‰¦1,000, in the presence: of at least one polycondensation catalyst H, optionally of a filler Z, and optionally of at least one diluent Jâ€² or solvent Jâ€³, and 2) by isolating the antimisting additive E, optionally after removal of the condensation catalyst H, and/or devolatilization and/or neutralization.
