A curable composition comprising (a) an organopolysiloxane comprising a curable functional group; (b) a cross-linker comprising a silyl hydride group or a thiol group; (c) a reaction accelerator; (d) optionally an inhibitor; and (e) optionally other additives. The curable composition exhibits high refractive index and optical clarity. The curable composition can be used to prepare a cured material that exhibits high refractive index, optical clarity, crack resistance, and low moisture vapor permeability.

Curable silicone composition and applications and uses thereof

Provided is a one part, dual curable composition comprising (A) a first acrylic functional polyorganosiloxane with at least one moisture curable functional group, (B) a second acrylic functional polyorganosiloxane, which may optionally contain a moisture curable functional group, and (C) a third functional polyorganosiloxane, which optionally contains an acrylic and moisture curable functional group. The combination of (A), (B), and (C) provides a composition that is both moisture curable and radiation curable and provides a material that is fast curing via the dual cure functionality and provides a cured material exhibiting a relatively low modulus, good adhesion, and optical clarity.
