Abstract
Provided herein is a curable granular silicone composition which has hot-melt properties, is particularly superior in flexibility and toughness at high temperatures from room temperature to about 150° C. in cured products such as overmolding, and provides a cured product that does not easily warp or become damaged even when integrally molded with an aluminum lead frame or the like. A curable granular silicone composition comprising: (A) organopolysiloxane resin microparticles having a curing reactive functional group; (B) a functional inorganic filler; and (C) a curing agent. The composition provides, upon curing, a cured material having a storage modulus at 25° C. and 150° C. of less than 2,000 MPa and less than 100 MPa, respectively, and a peak value of tan δ represented by the storage modulus/loss modulus (G′/G″), is 0.40 or more.
