Aqueous dispersions of a silicone crosslinkable into elastomeric state by elimination of water therefrom, include: (A) 100 parts of an oil-in-water emulsion of an alpha , omega -(dihydroxy)polydiorganosiloxane, stabilized with an anionic and/or nonionic surfactant; (B) 0.1 to 20 parts of an alkenyloxysilane; (C) 0.01 to 3 parts of a metal curing catalyst; and (D) 0 to 250 parts of a nonsiliceous inorganic filler material; and such emulsion having a pH of from 7 to 13 and a solids content of at least 40%; the subject emulsions are especially adapted for the production of paints and of silicone elastomer seals, and for the coating of pharmaceuticals, agricultural chemicals and food packaging materials.
