Abstract:
Process for combating the appearance of mist (misting) during the coating of flexible supports with at least one liquid silicone composition, said process comprising applying a liquid silicone coating composition to a flexible support with a roll coating device, the liquid silicone coating composition being obtained by mixing (a) a silicone phase having a viscosity &eegr; at 25Â° C. of less than 2000 mPaÂ·s comprising:Aâ€”at least one polyorganosiloxane (POS) capable of cross-linking; Bâ€”optionally at least one crosslinking organosilicon compound; Câ€”optionally at least one catalyst of the crosslinking reaction; with (b) noncellulose antimist particles, the particle size of which, given by their D50 (in &mgr;m), is such that: D50&lE;10, these antimist particles being incorporated in the liquid silicone composition in a proportion of at most 30% by weight, andoptionally with a liquid compound (D) comprising: i. a diluent and/or a solvent comprising a non-organosilicon or organosilicon organic compound which optionally is capable of reacting with the polyorganosiloxane (A), and/or ii. water.
