A curing reactive silicone gel is provided. The curing reactive silicone gel is obtained by primarily curing a composition containing the following components in a gel form and further having secondarily curing reactivity. (A) an organopolysiloxane having at least two curing reactive groups in one molecule; (B) optionally, an organohydrogenpolysiloxane; and (C) a curing agent.

Curing reactive silicone gel and use thereof

Disclosed is an active energy ray curable hot melt silicone composition that is non-flowable at 25&#xb0; C. and has a viscosity of 1,000 Pa&#xb7;s or less at 100&#xb0; C. The active energy ray curable hot melt silicone composition comprises: (A) a mixture of (A1) an organopolysiloxane having an aliphatic unsaturated bond-containing organic group and (A2) an organopolysiloxane optionally having an aliphatic unsaturated bond-containing organic group, (B) a compound having at least two mercapto groups in a molecule, and (C) a photoradical initiator. A cured product and a method of making a film are also disclosed.

Active energy ray curable hot melt silicone composition, cured product thereof, and method of producing film

A curable silicone composition comprises: (A) an organopolysiloxane represented by a specific average unit formula; optionally, (B) an organopolysiloxane represented by a specific average unit formula; (C) an organohydrogenpolysiloxane represented by a specific average composition formula; and (D) a hydrosilylation catalyst. A curable hot-melt silicone is obtained by subjecting the curable silicone composition to a hydrosilylation reaction to a degree that does not form a cured product. The curable hot-melt silicone is non-flowable at 25&#xb0; C. and has a melt viscosity at 100&#xb0; C. of 5000 Pa&#xb7;s or less. The curable silicone composition provides a cured product having excellent heat resistance and light resistance after being cured. The curable hot-melt silicone is non-flowable at room temperature, has low surface stickiness, and is readily melted by heating.
