Abstract
Aqueous silicone dispersions having a solids content of at least 40% by weight and crosslinkable into flameproofed elastomeric state by elimination of water therefrom, well adopted, e.g., as jointing material for the construction industry, comprise an oil-in-water emulsion (A) of an .alpha.,.omega.-(dihydroxy)polydiorganosiloxane stabilized by an anionic and/or nonionic surfactant, an effective amount of a crosslinking agent (B), a non-siliceous inorganic filler material (C.sub.1), borax hydrate powder (C.sub.2), optionally, a non-siliceous hydrated inorganic filler material (C.sub.3) and, also optionally, a metal curing catalyst (D).
