    摘要: The present invention provides a method for producing silicone rubber moldings composed of a uniform, smooth and hard exterior layer and a relatively soft interior portion. In accordance with this method the surfaces of the mold cavity are coated with an organohydrogenpolysiloxane containing at least two silicon-bonded hydrogen atoms before the curable organosiloxane used to form the interior portion of the molding is injected into the mold cavity and cured.

    摘要: Cohesive bonding between silicone rubber compositions and plastics is achieved using primer compositions comprising a solution of at least one member of a specified class of organotitanate esters in an organic liquid. Cohesive bonding of silicone rubber compositions to both plastic and metals is achieved by including at least one member from either of two specified classes of organosilicon compounds in the primer composition together with the organotitanate ester.

    摘要: Cured silicone rubber in the form of a finely divided powder is prepared by (1) dispersing a heat-curable liquid silicone rubber composition in water maintained at a temperature of from 0.degree. to 25.degree. C., (2) dispersing the resultant dispersion in a liquid heated to a temperature of at least 50.degree. C., and (3) recovering the resultant cured powder. The liquid silicone rubber composition is preferably maintained at a temperature of from -60.degree. to 0.degree. C. before being emulsified and said liquid is preferably water.

    摘要: Powdered, cured silicone rubber in the form of microfine particles is prepared by emulsifying a curable liquid silicone rubber composition in a mixture of water and a surfactant at a temperature of from 0 to 25 degrees C., dispersing the curable composition in water heated to a temperature of at least 25 degrees C. and recovering the resultant cured particles. The liquid silicone rubber composition is preferably maintained at a temperature of from -60 to 0 degrees C. before being emulsified.

    摘要: Because the present invention produces a toner-fixing roll by forming, directly or indirectly, a layer of thermal stabilizer-containing cured silicone rubber on the circumferential surface of a core and by then heating the cured silicone rubber layer at 270.degree. C. to 400.degree. C. for 15 minutes to 24 hours, said toner-fixing roll has excellent releasability with regard to fused toner without the use of silicone oil. Due to this, the silicone rubber-coated roll produced by the method of the present invention is appropriately employed as a toner-fixing roll in dry electrophotographic devices, that is, it is suitable for the heat-fixing roll or pressure roll and particularly for the heat-fixing roll.
