Title:
「通気性防水」被覆を生じさせるための架橋性シリコーンを主体とする逆エマルジョンの使用
Document Type and Number:
Japanese Patent JP2005517099
Kind Code:
A
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. The invention also concerns water impermeable and water vapor permeable soft polyamide or polyester substrates obtained by using an invert water-in-oil silicone emulsion.
