Abstract
The invention relates to a process for combating the appearance of mist (misting) during the coating of flexible supports with at least one liquid silicone (RTV polyaddition) composition which is a precursor of silicone coating(s) using a roll coating device operating at high speed. The targeted aim is to increase the speed of appearance of the misting and subsequently to improve the appearance, the coverage and the mechanical properties of the silicone coating and industrial hygiene. For this, use is made of a liquid coating composition obtained by mixing:a silicone phase comprising one or more POSs (A) and optionally one or more (crosslinking) compound(s) (B), the viscosity &eegr; of which at 25° C. is between 100 and 800 mPa·s;with 1 to 10% by weight of noncellulose antimist particles (talc, silica, kaolin, TiO2), the D50 (in &mgr;m) of which is: 0.01≦D50≦2;and optionally with a liquid (D)—water/solvent.
