Abstract: A method for covering a roof, the method comprising (i) providing first and second silicone membranes, where the membranes are in the form of rolls; (ii) unrolling the first and second silicone membranes over a roof surface; (iii) positioning first and second membranes adjacent to one another and overlapping and edge of the second over an adjacent edge of the first membrane to thereby form a lap; (iv) securing the first and second membranes to the roof surface; and (v) seaming the first membrane to the second membrane in the lap.

Abstract: A method of hydrophobing fillers such as inorganic pigments, metal oxides, metal hydroxides, and silicate minerals, involves contacting a filler with an oxa-silacycloalkane, until hydroxyl functionality on the filler is replaced with carbinol functionality (i.e. .tbd.C--OH). The preferred oxa-silacycloalkane is 2,2,4-trimethyl-1-oxa-2-silacyclopentane.

Abstract: The polymer latices of this invention are compositions formed by adding an unsaturated alkoxy silane and an initiator to a preformed emulsion polymer. The polymer latices have utility as protective surface coatings, adhesives, sealants and as vehicles for paint formulations.

Abstract: The present invention relates to hybrid aqueous silicone-organic composition which are prepared by first forming a silicone oil-in-water emulsion by dispersing an oil phase, containing a silicone polymer and a specific non-ionic surfactant, in a water phase containing a poly(vinyl alcohol) dissolved in water. This silicone emulsion is subsequently mixed with a an aqueous solution of a water-soluble polymer to form the instant compositions which can be applied to substrates to provide coatings having heat resistance comparable to conventional all-silicone systems delivered from organic solvent solution.

Abstract: A curable coating composition, which provides excellent corrosion protection to metals, is disclosed. The composition comprises (I) a reaction product (or blend) of a resinous copolymeric siloxane solution with a liquid organohydrogenpolysiloxane, (II) a hydroxy-functional diorganopolysiloxane, (III) an organosilane, (IV) a trialkyl orthoformate, (V) an organic titanate and (VI) a condensation catalyst. High solids compositions of the present invention can be applied by conventional siphon cup spray equipment and have an extended bath life relative to prior art formulations of this type.
