ABSTRACT:
A latex of crosslinked silicone is prepared by emulsifying a vinyl endblocked polydiorganosiloxane and an organosilicon compound having silicon-bonded hydrogen atoms with water and surfactant, adding a platinum catalyst and then heating the emulsion to form the latex. Colloidal silica can be added to the latex to provide a product which is tougher. The water in the latex can be evaporated to provide an elastomer film. Coating the latex on a substrate, such as a textile or paper, provides an elastomeric coated substrate, which provides water repellency, insulation and release properties to the substrate.
