    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: Room temperature curing organopolysiloxane composition which are paintable after curing can be made by mixing hydroxyl-terminated organopolysiloxane, a paintability compound which contains at least one X--R.sup.1 --O-- silicon-bonded group and at least one aminoxy or amido group bonded to a silicon atom where X is ##STR1## and R.sup.1 is a divalent hydrocarbon group, and a crosslinking compound which is a silicon compound having at least two silicon-bonded aminoxy and amido groups. These compositions can cure to low modulus sealing materials useful in building construction and by being paintable allow the color to be determined after installation rather than needing to select a pre-pigmented composition.

    摘要: Cured unitary molded articles containing conductive and insulating silicone rubber components are prepared by tightly contacting a curable insulating silicone rubber composition comprising a curable silicone rubber containing substantially no carbon black and a nonacyl-type peroxide with a cured conductive silicone rubber component containing carbon black and which has been cured by an addition reaction in the presence of a platinum-type catalyst and molding the resultant composition at elevated temperatures to cure the insulating silicone rubber component and form a unitary cured silicone rubber article.This invention also relates to cured silicone rubber articles prepared using the method of this invention.
