Granular curable silicone composition, cured product of same, and method for producing same

Abstract

Provided is a curable silicone composition that can contain a large amount of a functional inorganic filler, provides a cured product with excellent hot-melt, gap-filling, and homogeneity properties characterized by high fluidity at high temperatures, is suitable for transfer molding and other molding or sealing processes, generates little dust, and has excellent handling workability; a manufacturing method with excellent production efficiency and homogeneity; and the like. A granular curable silicone composition comprises: (A) an organopolysiloxane resin containing at least 20 mol % or more T units, (B) a curing agent, and (C) a functional inorganic filler. The amount of component (C) is 400 to 3000 parts by mass relative to 100 parts by mass of components (A) and (B). The composition is a solid at 25° C. and has a melt viscosity of 200 Pa·s or less, and the average particle size thereof is in the range of 0.1 to 10.0 mm.
