Patent ID: 8119758

Claim:
A heat-conductive silicone composition, comprising: (A) 100 parts by volume of an organopolysiloxane represented by an average composition formula (1) shown below: R 1 a SiO (4-a)/2 (1) (wherein, R 1 represents identical or different, unsubstituted or substituted monovalent hydrocarbon groups of 1 to 18 carbon atoms, and a represents a number within a range from 1.8 to 2.2), (B) 0.1 to 50 parts by volume of an organosilicon compound represented by a general formula (2) shown below: (wherein, R 2 represents an unsubstituted or substituted alkyl group, alkenyl group or aryl group, wherein a number of carbon atoms within R 2 is within a range from 6 to 30, each R 3 represents, independently, an unsubstituted or substituted alkyl group, alkenyl group or aryl group, R 4 and R 5 each represent identical or different, unsubstituted or substituted monovalent hydrocarbon groups, and numbers of carbon atoms within R 3 , R 4 and R 5 are independently, within a range from 1 to 8, each R 6 represents, independently, a hydrogen atom, or an unsubstituted or substituted monovalent hydrocarbon group, each R 7 represents, independently, an unsubstituted or substituted alkyl group, alkoxyalkyl group, alkenyl group or acyl group, m represents an integer from 2 to 4, and n represents an integer from 2 to 20), (C) 100 to 2,500 parts by volume of a heat-conductive filler, and (D) an effective quantity of a curing agent.
