Abstract:
A pressure sensitive adhesive emulsion comprising a disperse silicone phase emulsified in a continuous water phase in the presence of a surfactant; the disperse silicone phase comprising 40-80 percent by weight of a silicone pressure sensitive adhesive, the silicone pressure sensitive adhesive being the product obtained by mixing a silanol terminated polydiorganosiloxane of Tg below âˆ’20Â° C. with a silanol containing silicone resin of Tg above 0Â° C., the silicone pressure sensitive adhesive being dispersed in 60-20 percent by weight of a volatile silicone fluid having a boiling point below 300Â° C.; the emulsion being free of any non-silicon atom containing volatile organic material.
