摘要

An aqueous silicone dispersion crosslinking to an elastomer on removal of water, comprising: - 100 parts of an emulsion (A) of the oil-in-water type of an alpha , omega -(dihydroxy)polydiorganosiloxane stabilised with an anionic and/or nonionic surfactant, - 0.1 to 15 parts of an organosiliconate, - 5 to 250 parts of a non-siliceous inorganic filler, - 0.01 to 3 parts of a catalytic tin salt, the said dispersion having a pH of between 8.5 and 13 and a solids content of at least 40%. Use of the dispersions for the production of silicone elastomer seals, in particular for building.
