A photocurable silicone composition is disclosed. A cured product of the composition is also disclosed, as well as methods of forming the same. The photocurable silicone composition comprises: (A) a specific organopolysiloxane having alkenyl groups in a molecule; (B) a compound having at least two thiol groups in a molecule; (C) a photoradical initiator having a phosphorus atom; and (D) a specific hydroxyphenyl triazine compound. The composition exhibits excellent curability by LED lamp with wide UV-Visible range as well as metal-halide lamp, and cures to form a cure product exhibiting excellent resistance to light.

Photocurable silicone composition and cured product thereof

A silicone back plate for a flexible display is disclosed herein. The silicone back plate is formed by a cured silicone product having from 70 to 95 of a Shore A hardness measured in accordance with ASTM D2240, and having at least 10 MPa of a tensile strength and at least 30% of an elongation measured in accordance with ASTM D412. The silicone back plate can provide the flexible display with reliability.

A curable silicone composition is disclosed herein. The curable silicone composition comprises: (A) an alkenyl group-containing organopolysiloxane comprising (A) a linear organopolysiloxane having at least two alkenyl groups per molecule, and (A) a resinous organopolysiloxane; (B) a silicon atom-bonded hydrogen atom-containing organopolysiloxane comprising (B) a resinous organopolysiloxane, (B) a linear or partially branched organopolysiloxane having at least two silicon atom-bonded hydrogen atoms per molecule, and having not less than 0.5 mass % of silicon atom-bonded hydrogen atoms, and (B) a linear organopolysiloxane having at least two silicon atom-bonded hydrogen atoms per molecule, and having less than 0.5 mass % of silicon atom-bonded hydrogen atoms; and (C) a hydrosilylation reaction catalyst. The curable silicone composition can be cured to form a cured product generally exhibiting good elongation and tensile strength.
