Abstract
Aqueous silicone dispersions crosslinkable into elastomeric state upon removal of water therefrom, well adapted for the production of paints and silicone elastomer seals, e.g., for the construction industry, include: PA0 (A) 100 parts by weight of an oil-in-water emulsion of an .alpha.,.omega.-(dihydroxy)polydiorganosiloxane, stabilized with an anionic and/or nonionic surfactant; PA0 (B) 0.1 to 20 parts by weight of an aminosilane and/or amidosilane; PA0 (C) 0 to 3 parts by weight of a metal curing catalyst; and PA0 (D) 0 to 250 parts by weight of a non-siliceous inorganic filler, such emulsion having a pH of from 7 to 13 and a dry solids content of at least 40%.
