Abstract: A method for improving the overall performance of grinding wheels containing cubic buron nitride abrasives through the application of an organopolysiloxane fluid to the point of contact between the grinding wheel and a workpiece being subjected to the action of such grinding wheel. The organopolysiloxane fluid is non-toxic, and non-flammable and functions as a lubricant and coolant in the grinding process.

Abstract: A process for recovering and recycling elementary silicon from a direct process organohalosilane reactor system is provided, comprising the steps of analyzing a portion of effluent contact mass, such as the silicon fines from a secondary cyclone with a particle size distribution analyzer, determing the fines fractions containing the relatively greatest amounts of impurities and segregating a relatively impure fine fraction from a purer coarse fraction with the aid of an aerodynamic centrifugal classifier.

Abstract: A silicone rubber composition with a good shelf life and fast curing at elevated temperatures comprising a silanol end-stopped diorganopolysiloxane polymer, a silicone hydride and a rhodium complex catalyst in combination with an inhibitor compound selected from low molecular weight silanol end-stopped diorganopolysiloxanes, acetylenic compounds, olefinic carboxylic acid esters of aliphatic alcohols, alkenyl isocyanurates and mixtures of the above inhibitor compounds. The above compositions are especially suited as release coatings for plastic and cellulosic subtrates including paper.

Abstract: A silicone resin-mica composite comprising an organosiloxane resin, a mixture of acid phosphates and mica.
