Abstract
The present invention is directed to an aqueous silicone dispersion capable of being crosslinked into a transparent elastomer comprising: 1) a silicone phase comprising at least one crosslinkable polyorganosiloxane A, optionally at least one silicon-containing adhesion promoter B, optionally at least one crosslinking agent D, and optionally at least one solvent Sa of the crosslinkable polyorganosiloxane A, 2) a non-silicone hydrophilic phase comprising at least one filler, a surfactant, and optionally at least one catalyst and/or at least one water soluble adhesion promoter B′, and 3) water; wherein the difference between the refractive indexes of component 1) and component 2) is not greater than 0.05, preferably not greater than 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.
