Photocurable silicone composition and cured product thereof

Abstract

A photocurable silicone composition is disclosed. A cured product of the composition is also disclosed. The photocurable silicone composition comprises: (A) an organopolysiloxane having at least one aryl group with 6 to 12 carbons and at least one alkenyl group with 2 to 12 carbons in a molecule; (B) an organic compound having at least two ether bonds and at least one aliphatic carbon-carbon double bond in a molecule; (C) a thiol group-containing organic compound comprising; (C1) an organic compound having two thiol groups in a molecule, and (C2) an organic compound having at least three thiol groups in a molecule; and (D) a photoradical initiator. The composition generally suppresses crack and delamination of a cured product laminated between two substrates after thermal aging.
