Abstract

See full text

This thermally conductive silicone composition contains:

    (A) 100 parts by mass of a diorganopolysiloxane in which both terminals of a molecular chain are blocked with hydroxy groups;(B) 150-600 parts by mass of an organopolysiloxane with a particular structure having at least one hydrolyzable silyl group in one molecule;(C) 0.1-100 parts by mass of a crosslinking agent component;(D) 1,500-6,500 parts by mass of zinc oxide particles which have an average particle diameter of 0.1 μm to 2 μm, and in which the content ratio of a coarse powder having a particle diameter of 10 μm or more in a laser diffraction-type particle size distribution is 1 vol % or less with respect to the total amount of component (D); and(E) 0.01-30 parts by mass of an adhesion promoter, wherein the content of component (D) is 45-70 vol % with respect to the total composition.
