摘要： An aqueous silicone emulsion forms a resin reinforced elastomeric film upon water evaporation. The emulsion composition contains a dispersed phase consisting of a silicone mixture composed of (i) a linear hydroxy terminated polydiorganosiloxane, (i) a silicone MQ resin, and (iii) an organofunctional polysiloxane. The aqueous silicone emulsion is prepared by mixing ingredients (i) to (iii) to form a mixture, adding emulsifiers and water to the mixture, mixing the ingredients to obtain an aqueous base emulsion, adjusting the pH of the base emulsion to an acidic or basic pH to facilitate crosslinking, and subsequently neutralizing the emulsion. Elastomeric films can be obtained by drying the emulsion on a substrate at ambient conditions.
