ADDITION-CURABLE SILICONE COMPOSITION AND OPTICAL ELEMENT

摘要

PURPOSE: An addition-curable silicone composition and an optical element are provided to enhance strength and optical element strength. CONSTITUTION: An addition-curable silicone composition comprises a linear organopolysiloxane having 2 or more silicon atom bond aliphatic unsaturated groups and one or more silicon atom bond CF3 - (CF2) m - (CH2) n-, an organopolysiloxane having a branched structure of siloxane unit represented by SiO4/2 and/or RSiO3/2, 2 or more silicon atom bond aliphatic unsaturated groups and one or more silicon atom bond CF3 - (CF2) m - (CH2) n-, an organosilicon compound having 2 or more silicon atom bond hydrogen atoms, and a platinum based metal system catalyst.
