Abstract
A shelf stable aqueous silicone emulsion which yields an elastomer upon removal of the water is produced by combining a reactive polydiorganosiloxane present as a cationic or nonionic emulsion of dispersed particles in water, a crosslinker, and a tin catalyst, the tin catalyst being in the form of a divalent tin atom combined with organic radicals. The emulsion can be reinforced with colloidal silica without effecting the shelf life of the reinforced emulsion.
