<p>The invention concerns a method for preventing misting when coating flexible supports with at least a liquid silicone (RTV polyaddition) composition precursor of silicone coating(s), with a coating device comprising rollers operating at high speed. The invention aims at increasing misting speed and consequently enhancing the appearance, the mechanical properties of the silicone coating, as well as industrial hygiene. Therefor, it consists in using a liquid coating composition obtained by mixing: a silicone phase comprising one or several POS (A) and optionally one or several (crosslinking) compound(s) (B) having a viscosity θ at 25 °C ranging between 100 and 800 mPa's; with 1 to 10 wt. % of an anti-misting aqueous silicone (water-in-oil) emulsion having an aqueous phase ζa comprising at least 20 wt. % of water; and optionally with a water/solvent liquid (D).</p> |
