Abstract: Silicone coating on various soft supports, for instance textiles, made of synthetic polymers (polyamide, polyester) provides an efficient method for producing water impermeable and water permeable coatings, on soft supports, said method enabling to improve permeability to water vapor of the silicones while preserving impermeability to water. The inventive method enabling this consists mainly in: coating one of the surfaces of the support with a film formed by an invert water-in-oil silicone emulsion comprising a continuous oily silicone phase phi s, crosslinkable into elastomer and including a polyorganosiloxane (POS) A crosslinkable by addition polymerization, by cationic process or free-radical process; optionally a crosslinking organosilicon compound B; and optionally at least a catalyst C; an aqueous phase phi a; a stabilizing agent; and in ensuring crosslinking of the silicone phase phi s and elimination of water.

Abstract: Oil-in-water siloxane emulsions are useful for providing a substrate, especially a textile substrate, with long-lasting water-repellent properties.

Abstract: An essential aim of the invention is a treatment which permits: (i) coating a textile material and/or threads, fibers and/or filaments making up the textile material, the silicone formulation cross-linking around the threads, fibers and/or filaments making up the textile material and forming a cross-linked silicone coating around the same and ii) durably imparting water-repellency and impermeability to said textile material without substantially affecting the intrinsic respirability of the textile material. Said aim is achieved by means of the present invention using at least one cross-linkable silicone formulation as a base for the textile coating material, particularly, of a textile material which may be used for the production of sports clothing.
