    摘要: A curable silicone composition which is composed of at least (A) an organopolysiloxane having at least two silicon atom-bonded alkenyl groups in each molecule, (B) an organopolysiloxane having at least two silicon atom-bonded hydrogen atoms in each molecule, (C) at least one fine powder that is selected from the group consisting of fine zinc oxide powders that are surface-coated with an oxide and/or hydroxide of at least one element that is selected from the group consisting of Al, Ag, Cu, Fe, Sb, Si, Sn, Ti, Zr and rare earth elements, fine zinc oxide powders that are surface-coated with an organosilicon compound having no alkenyl group, and fine powders of zinc carbonate hydrates, and (D) a catalyst for hydrosilylation reaction. This curable silicone composition has excellent storage stability, and is cured to form a cured product that is suppressed in yellowing due to thermal aging and that sufficiently suppresses discoloration of a silver electrode or silver plating of a substrate in an optical semiconductor device, said discoloration being caused by a sulfur-containing gas in the air

    摘要: A two-part curable liquid silicone rubber composition is composed of a first liquid composition and a second liquid composition, which are stored separately and yield upon mixing a silicone rubber-forming composition. The silicone rubber-forming composition comprises: (A) a diorganopolysiloxane having an average of at least 2 alkenyl groups in a molecule; (B) a silicon-bonded hydrogen atom-containing organopolysiloxane composed of (B-1) an organopolysiloxane having an average of not more than 2 silicon-bonded hydrogen atoms in a molecule only in side molecular chains and (B-2) an organopolysiloxane having 2 silicon-bonded hydrogen atoms only at both molecular terminals; (C) a calcium carbonate powder; and (D) a platinum-based catalyst. The two-part curable liquid silicone rubber composition provides a cured product with suppressed fluctuations of properties even if the mixing ratio of a first composition and a second composition is changed.
