Aqueous dispersions of organopolysiloxanes comprising (A) an organopolysiloxane containing groups which are capable of condensation, (B) a condensation catalyst, (C) an organopolysiloxane resin which is at least partly soluble in organopolysiloxane (A) when present in amounts of up to 50% by weight based on the weight of (A), (D) a compound containing basic nitrogen and (E) polyvinyl alcohol. The aqueous dispersions are prepared by dissolving the organopolysiloxane resin (C) in the organopolysiloxane (A) and then emulsifying the solution with polyvinyl alcohol (E) and water. The stable aqueous dispersions of the present invention cure to form transparent films.

Aqueous dispersions of organopolysiloxanes

The present invention relates to compositions which crosslink to give elastomers, which are based on component (A) comprising polyorganosiloxane (I) having at least two alkenyl groups per molecule, at least one hydroxyl-group-containing compound and a metallic catalyst (V) and component (B) comprising polyorganosiloxane (II) having at least two silicon-bonded hydrogen atoms and organic sulfur compound (VI).

RTV-2 silicone foams with low compression set

The use is described of boron compounds chosen from the group consisting of boron carbide and metal borides mixed with non-reinforcing fillers, with the proviso that at least 75% by weight of the non-reinforcing fillers are heat-stable up to 1200.degree. C., as flameproofing agents in organopolysiloxane compositions which can be crosslinked to flame-resistant elastomers.
