ABSTRACT:
Method for preparation of an aqueous emulsion from a curable silicone composition consisting of (A) an organopolysiloxane having at least two silicon-bonded hydroxyl groups, (B) an organohydrogensiloxane, and (C) a curing catalyst, said method being characterized by (i) continuously supplying component (A), component (B) and component (C), or a mixture of components (A) and (B) and component (C) through individual inlet ports into a continuous mixer and mixing said components at a temperature not exceeding 10° C., (ii) continuously supplying the obtained mixture and (D) an aqueous solution of a surface-active agent to an emulsifier, and emulsifying the components at a temperature not exceeding 20° C. An apparatus for the preparation of an aqueous emulsion of a curable silicone composition comprising of a continuous mixer for mixing components (A) through (C), a distribution unit connected to the lower part of the mixer, and an emulsifier. Method for preparation of a suspension of cured silicone particles by allowing such emulsion to stand at room temperature, or heating the aforementioned emulsion.
