A process for the preparation of an aqueous 1-component silicone composition

A process for preparing a silicone on drying an elastic network-forming, aqueous 1-component composition, wherein containing I) stabilized with a surfactant dispersion containing silicone compound (Ia) which units of the formulas (Ia-1) and (Ia-2) 30 to 100 mol% of R 20 to 100 mol% of (R , said R can be the same or different and are a hydrogen atom or an Si-C bonded C R a has the values ​​0 and 1 and b is 0; 1; can take 2 and 3 With II) with a surfactant-stabilized emulsion of silicone oil, which carries reactive groups selected from silanol, hydrocarbyloxy and silica species is reacted in the presence of a heterogeneous catalyst at least 40 ° C and in which the heterogeneous catalyst is removed again after the reaction.
