    摘要: A room temperature curable rubber composition of a condensation curing type that comprises as a base polymer a diorganopolysiloxane or a polyoxyalkylene in which both ends of the molecular chain are blocked with a hydrolyzable silyl group, and a .beta.-dicarbonyl compound and an amino group containing organic compound that are blended with the base polymer. Since the room temperature curable rubber composition is cured with water in the air and at the same time the dehydration condensation of the .beta.-carbonyl group and the amino group produces water in the composition, the quick curability and deep curability are improved remarkably. In addition, since this dehydration condensation reaction is an irreversible reaction, the product produced by the condensation dehydration is hydrolyzed to prevent the amino group containing compound from being regenerated, and as a result the hydrophilic nature of the cured product is prevented from increasing not to damage the water resistance.

    摘要: Provided is a room temperature-curable, heat-conductive silicone rubber composition, including: (A) a diorganopolysiloxane with both molecular chain terminals blocked with hydroxyl groups and/or organooxy groups, (B) a heat-conductive filler other than a palladium powder, (C) an organosilane containing two or more hydrolyzable groups, and/or a partial hydrolysis-condensation product thereof, and (D) a palladium powder. The composition improves on the drawbacks of the conventional technology, is able to suppress the quantity of hydrogen gas produced from the heat-conductive filler, exhibits superior storage properties, and yields a low-hardness cured product upon curing. The cured product is useful as a heat-conductive material for a heat-generating electronic component.
