PRECURED SILICONE EMULSION AND METHOD FOR PREPARATION

摘要

An aqueous silicone emulsion is described which provides an elastomeric product upon removal of the water under ambient conditions. The emulsion comprises a continuous water phase and a dispersed phase of crosslinked silicone. The silicone phase is the product of radical produced crosslinking of hydroxyl endblocked polydiorganosiloxane. The polydiorganosiloxane is crosslinked after it has been dispersed in water. Preferred polydiorganosiloxanes contain vinyl-substituted siloxane units and can be crosslinked by high energy radiation or the combined action of heat and an organic peroxide.
