摘要： This invention relates to a method of sealing openings in structural components of a building to reduce the amount of smoke which may pass through the opening in the event of a fire. The method comprises filling an opening in a structural component of a building with a support material; applying a coating of a silicone composition over the filled opening and allowing the silicone composition to cure into a continuous elastomeric film having certain properties. These silicone compositions exhibit pseudo plastic rheology which facilitates their application by spraying.

摘要： 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.
