    • The invention discloses a silicon and organic (co)polymer latex based aqueous dispersion, cross-linking by eliminating water through drying in ambient conditions into an elastomer with adjustable translucency having high mechanical properties, characterised in that it is not provided with any reinforcing mineral filler and in that it comprises the following constituents: (A) an oil-in-water emulsion with 100 parts by weight of an oil or a polymer alpha , omega -(dihydroxy)polydiorganosiloxane (A1) and 1 to 100 parts by weight of an organosilicic cross-linking agent (A2), the said emulsion being stabilised by at least one surfactant (A3) selected among anionic and non-ionic surfactants and their mixtures; and with a particle size between 0.1 mu m (100 nm) and 100 mu m (100000 nm); and having a dry extract content of at least 60 wt.%; (B) for 100 parts by weight of oil or polymer (A1), 1 to 100 parts by weight of an aqueous dispersion of at least an organic (co)polymer with a particle size of 0.01 mu m (10 nm) to 10 mu m (10000 nm), and a dry extract of 10 to 70 wt.%; (C) optionally, for 100 parts by weight of oil or polymer (A1), 0.01 to 5 parts by weight of a hardening catalytic metal compound. The dispersions are useful in producing translucid silicon elastomers for the building industry.
