Process for combating the appearance of mist during the coating of flexible supports with a crosslinkable liquid silicone composition in a roll device.

Process for combating the appearance of mist (misting) during the coating of flexible supports with at least one liquid silicone composition which is a precursor of silicone coating(s) using a roll coating device,

• the liquid composition comprising:
• A—at least one polyorganosiloxane (POS) which can be crosslinked by polyaddition, by polycondensation, by the cationic route or by the radical route
• B—optionally at least one crosslinking organosilicon compound
• C—optionally at least one catalyst of the crosslinking reaction;
• characterized in that 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)
• and the viscosity η of which at 25° C. is less than 2 000 mPa.s;
• with noncellulose antimist particles, the particle size of which, given by their D50 (in μm), is such that:
• D50≦10,
• these antimist particles being incorporated in the liquid silicone composition in a proportion of at most 30% by weight,
• and optionally with a liquid compound (d) composed:
• i. of a diluent and/or a solvent comprising a non-organosilicon or organosilicon organic compound which may or may not be capable of reacting with the compound(s) (A),
• ii. and/or of water, in the case of the use of an emulsified system.
