Process For Producing Silicone Compositions Comprising Finely Divided Fillers

A process for producing silicone compositions containing surface-treated, finely divided fillers, comprising

• (a) mixing of a surface-treated, finely divided filler (A) with a polyorganosiloxane (B) in the presence of a low molecular weight organosilicon compound (C) which has from 2 to 10 silicon atoms and contains no hydrolyzable or condensable functional groups, or
• (b) mixing a composition comprising a surface-treated finely divided filler (A) and a polyorganosiloxane (B), with a low molecular weight organosilicon compound (C) which has from 2 to 10 silicon atoms and contains no hydrolyzable or condensable functional groups,
• and removing the low molecular weight organosilicon compound (C) to an extent of at least 80% based on the amount of low molecular weight organosilicon compound (C) from the filler-containing silicone composition, wherein the surface-treated, finely divided filler (A), the polyorganosiloxane (B) and the organosilicon compound (C) are each a single substance or a plurality of substances.
