Abstract:
1. A curable silicone composition comprising (A) 100 mass parts of an alkenyl-containing organopolysiloxane comprising (B) an organopolysiloxane that has an average of at least three silicon-bonded hydrogen atoms in each molecule wherein the silicon-bonded groups other than the silicon-bonded hydrogen are C (C) a hydrosilylation reaction catalyst in a catalytic quantity, and provides a highly transparent cured silicone material that has a hardness measured using the type A durometer specified in JIS K 6253 is in the range from at least 30 to not more than 80, the elongation as specified in JIS K 6251 is at least 50%, the parallel light transmittance at 25° C. measured in accordance with JIS K 7105 on a 6 mm optical path length is at least 90%, and the parallel light transmittance at 200° C. is a value that is at least 99% of the parallel light transmittance at 25° C.
