Abstract: Thixotropic silicone emulsions crosslinkable into elastomeric state upon removal of water therefrom, e.g., to fabricate elastomer seals for the construction industry, have a pH of from 4 to 8 and a solids content of at least 50%, and contain:(A) 100 parts of an oil-in-water emulsion of an .alpha.,.omega.-(dihydroxy)polydiorganosiloxane, and a stabilizing amount of at least one anionic or nonionic surface-active agent, or mixture thereof;(B) 1 to 15 parts of a siliceous reinforcing filler in powder form;(C) 0 to 250 parts of an inorganic filler other than the siliceous filler (B);(D) 0.01 to 2 parts of a catalytic tin compound; and(E) 0.1 to 5 parts of boric oxide, a boric acid or a borate.

Abstract: Methylphenylsiloxane coating compositions comprising silica fillers and aluminum particulates, e.g., matte paints, are well adopted for the provision of hard nonadhesive finishes, e.g., on kitchen utensils.

Abstract: Novel organopolysiloxane compositions, well adopted for use as mold release coatings, are comprised of (A) a particular diorganopolysiloxane oil containing methyl, phenylalkyl or alkyl radicals having from 7 to 15 carbon atoms, (B) an MQ organopolysiloxane copolymer resin, and (C) an inert organic diluent therefor.

Abstract: Aqueous dispersions of particulate polyvinylbutyral are disclosed, said dispersions comprising an amount of hydrosolubles dissolved in the aqueous phase thereof, the content in the dispersions of said dissolved hydrosolubles being less than about 2.5% by weight, based upon the weight of the polyvinylbutyral. Said dispersions are useful in the formulation of certain coating compositions, e.g., paints and varnishes.

Abstract: A method of preparing a plasticizer-free aqueous dispersion of polyvinylbutyral is disclosed. The method effects simultaneous butyralization and dispersion, forming aqueous dispersions of polyvinylbutyral having a particle size between 0.01 and 5.mu.. The dispersion exhibits utility in protective coatings for metallic support surfaces.
