Title (EN) SILICONE DISPERSIONS
(FR) DISPERSIONS DE SILICONE
Abstract:
(EN) A non-aqueous silicone emulsion is provided. It comprises a continuous phase of a polar organic liquid containing droplets of an organopolysiloxane dispersed therein. An organic wax, which has a melting point in the range 40 to 100°C and is sparingly soluble in the polar organic liquid at 25°C, is dispersed in the polar organic liquid continuous phase as a network of interconnected particles which stabilises the organopolysiloxane droplets in emulsion in the polar organic liquid. A process for the production of the emulsion is also disclosed.
(FR) L'invention concerne une émulsion non aqueuse de silicone. L'émulsion comprend une phase continue constituée d'un liquide organique polaire dans lequel des gouttelettes d'organopolysiloxane sont dispersées. Une cire organique, dont le point de fusion est situé dans la plage allant de 40 °C à 100 °C et qui est peu soluble dans le liquide organique polaire à 25 °C, est dispersée dans la phase continue constituée du liquide organique polaire sous la forme d'un réseau de particules interconnectées qui stabilise les gouttelettes d'organopolysiloxane en émulsion dans le liquide organique polaire. Un procédé de production de l'émulsion est également décrit.
