摘要

(57) An aqueous silicone dispersion which can be in the elastomer by crosslinking by removing the alcohol and carboxylic acid or / SUMMARY water, optionally, the dispersion is condensable at least two per molecule or polyorganosiloxane of one 1 (A), and I want to base one surfactant (B) is at least having a group (alkyl or R a = H) hydrolyzable OR a. Is the dispersion, the technical problem of having to prepare a stable dispersion can be elastomers having mechanical properties and economical The stable and are adherent extremely support on any and by crosslinking and hydroxylated at least one polyorganosiloxane which is amino-functionalized DTT being redistributed by aminoethyl aminopropyl trimethoxysilane (N) of (OMe) resin type (C), and optionally the alkoxylated and / or silica optionally at least one and optionally (F) a condensation catalyst at least one alkoxysilane of the type (E), optionally at least to impart OR a terminated polydiorganosiloxane of the silicone resin (A) was (D), optionally because they contain a (G) quality filler, to resolve. The dispersion is a useful mastic, as a coating or adhesive film and sealing material.
