摘要： Cured silicone rubber powder containing large amounts of particulate material formed by dispersing a liquid silicone rubber composition curable by a platinum-catalyzed hydrosilation reaction into water. The presence of a low molecular weight, volatile polydiorganosiloxane makes it possible to incorporate at least 100 parts by weight of particulate material per 100 parts of curable polydiorganosiloxane into the composition. The volatile polydiorganosiloxane is removed from the cured polwder. Finely divided magnetic metals, electrically conductive materials and reinforcing silica powders can be incorporated using the present method.

摘要： Curable fluororubber compositions exhibit excellent processability on roll mills and can be molded without sticking to or staining the mold surfaces when the composition contains from 0.1 to 30 weight parts per 100 weight parts of fluororubber of a finely divided cured silicone material in the form of a rubber, gel or resin. An epoxy-substituted alkoxysilane or a partial hydrolysis product thereof is present as an ingredient of the curable composition when it is desired to cohesively bond the cured fluororubber to a metal or plastic substrate.
