Abstract

Abstract Translated from French Composition organopolysiloxane réticulable en couche mince par réaction d'hydrosilylation pour l'enduction de matériau souple comportant un organopolysiloxane vinylé, un organopolysiloxane hydrogéné, un catalyseur d'un métal du groupe du platine, caractérisée en ce qu'entre 0,5 et 60 % en nombre des groupes vinyle sont apportés par un vinylorganocyclotrisiloxane. La composition de l'invention est plus particulièrement utilisable pour l'antiadhérence de support souple, en particulier des feuilles de papier. Organopolysiloxane composition crosslinkable in a thin layer by hydrosilylation reaction for coating flexible material comprising a vinylated organopolysiloxane, a hydrogenated organopolysiloxane, a catalyst of a platinum group metal, characterized in that between 0.5 and 60% in number of the vinyl groups are provided by a vinylorganocyclotrisiloxane. The composition of the invention is more particularly usable for the anti-adhesion of flexible support, in particular sheets of paper.
