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).

Abstract: 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.

Abstract: Aqueous dispersions of a silicone, crosslinkable into elastomeric state upon removal of water therefrom under ambient conditions, well adapted for formulation into paints and for the production of silicone elastomer seals, include (A) 100 parts by weight of an oil-in-water emulsion containing a stabilizing amount of at least one anionic and/or nonionic surfactant and at least one alkoxylated diorganopolysiloxane, (B) an effective amount of an inorganic siliceous or nonsiliceous filler material, and (C) a catalytically effective amount of a metal curing catalyst.

Abstract: 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 15 parts of an organosiliconate; and(C) 5 to 250 parts of a nonsiliceous inorganic filler material; and such emulsion having a pH higher than 7 and a solids content of at least 40%; the subject emulsions are especially adapted for the production of silicone elastomer seals for the coating of food packaging materials.
