Abstract
The present invention relates to an aqueous silicone dispersion, capable of being cross-linked into an elastomer by removing water and optionally alcohol and/or carboxylic acid, said dispersion being based on at least one polyorganosiloxane (A) having at least two condensable or hydrolysable OR.sup.a groups per molecule wherein R.sup.a =H or alkyl, as well as at least one surficant (B). The technical problem consisting of perfecting a stable dispersion capable of being cross-linked into an elastomer that is highly adhesive on any support and that has suitable and economic mechanical properties is solved since this dispersion includes an amino-functionalised polyorganosiloxane (C) of the DTT(N)(OMe) resin type redistributed with aminoethylaminopropyltrimethoxysilane, optionally at least one hydroxylated and/or alkoxylated silicone resin (D), optionally at least on alkoxysilane (E) donating the -OR.sup.a terminals of the polydiorganosiloxane (A), optionally at least on condensation catalyst (F) and optionally at least one optionally siliceous filler (G).
