Abstract

The invention relates to compositions which can be prepared from at least one polyorganosiloxane, boric acid and water, and which may serve as a pelletizing additive for crosslinkable silicone rubber formulations. A small proportion of the pelletizing additive, when added to a ore component crosslinkable silicone rubber, or to individual components of a two or more component silicone rubber formulation, allow production of free flowing pellets which retain storage stability for extended periods of time.
