PROBLEM TO BE SOLVED: To provide a granular silicone cured product which has a peculiar viscoelasticity and gives a good feel, and a preparation process thereof. SOLUTION: The granular silicone cured product, which has an average particle size of from 0.1 to 500μm, is prepared by curing (A) 100 pts.wt. polydiorganosiloxane having at least two silicon atom-bound alkenyl groups within a molecule, (B) from 1 to 50 pts.wt. polyorganosiloxane resin of the formula: (R3SiO1/2)x(SiO4/2)1.0 (wherein multiple R are each an identical or different monovalent hydrocarbon group; and x is from 0.6 to 4.0) and (C) a polyorganosiloxane having at least two silicon atom-bound hydrogen atom within a molecule at an amount which cures component (A) or components (A) and (B) through crosslinking} using a catalytic amount of (D) a platinum catalyst. In the preparation process of the granular silicone cured product, 100 pts.wt. component (A), from 1 to 50 pts.wt. component (B) and component (C) at an amount which cures component (A) or components (A) and (B) through crosslinking} are dispersed in water by an emulsifier and cured using a catalytic amount of component (D). |
