Title (EN) EMULSIONS OF HIGH VISCOSITY SILICONE POLYETHERS
(FR) ÉMULSIONS DE POLYÉTHERS DE SILICONE À VISCOSITÉ ÉLEVÉE
Abstract:
(EN) A process is disclosed for making an aqueous emulsion of a silicone polyether having a viscosity greater than 10 kPa-s at 25QC by combining; an SiH terminated silicone polyether copolymer having an HLB of less than 7, an organopolysiloxane having terminal unsaturated groups, a hydrosilylation catalyst, and an emulsifier to form an oil phase, and then admixing water to the oil phase to form an emulsion.
(FR) L'invention concerne un procédé de fabrication d'une émulsion aqueuse d'un polyéther de silicone dont la viscosité est supérieure à 10 kPa-s à 25 QC en combinant un copolymère de polyéther de silicone à terminaison SiH avec un HLB inférieur à 7, un organopolysiloxane ayant des groupes non saturés terminaux, un catalyseur d'hydrosilylation et un émulsifiant pour former une phase huileuse, et en ajoutant ensuite de l'eau à la phase huileuse pour former une émulsion.
