Abstract (en)

[origin: FR2780067A1] The invention concerns silicone compositions capable of being hardened by cross-linking and used, in particular as sealant or waterproofing and/or fireproofing and/or jointing coats. In particular, the invention concerns an aqueous silicone dispersion crosslinkable into a transparent elastomer, comprising: (i) a silicone phase phi s with refractive index ns and comprising: at least one crosslinkable polyorganosiloxane (POS) A; optionally at least a silicon-containing adhesion promoter B; optionally at least a crosslinking agent D; provided that at least one of the constituents A, B, D of phi bears at least three functions of molecular crosslinking; and optionally at least one solvent Sa of the POS A silicone(s); (ii) a non-silicon hydrophilic phase phi H, with refractive index nH and comprising at least a CH filler, a surfactant TA and, optionally, at least a catalyst and/or at least a water-soluble adhesion promoter B'; (iii) and water. The invention is characterised in that: | ns- nH | </= 0.05 preferably, | ns nH | </= 0.04. The invention also concerns the method for preparing said dispersion, and the sealant or other materials or waterproofing/fireproofing coats comprising said dispersion.
