ABSTRACT:
This invention relates to sprayable aqueous silicone emulsions which form silicone elastomers upon the removal of water having improved smoke and fire resistant properties. The aqueous silicone emulsion comprises water, a product of a diorganosiloxane polymer and a crosslinker, a surfactant and a filler selected from the group consisting of aluminum trihydrate, fumed titanium dioxide, magnesium oxide, ceramic fillers and zinc borate. The silicone emulsion has a viscosity of 10,000 to 120,000 mPa s and exhibits pseudo plastic rheology which facilitates its application by spraying. A softening agent may also be added for modulus control.
