The present invention discloses an additive type single-form cure type thermally conductive polyxanthoxy grease composition containing the following as an indispensable component: (A) an organopolysiloxane having at least one alkenyl group per molecule And has a 50mPa at 25 ° C. s to 100,000mPa. (B) an organohydrogen polyoxyalkylene having at least two hydrogen atoms bonded to a ruthenium per molecule, which does not have an R 2 SiO unit, which does not have a hydrogen atom bonded to ruthenium at any terminal, It has only one or more side chains having a hydrogen atom bonded to a hydrazine, and it is in a substantially linear form in an amount such that the number of {Si-H groups}/{the number of alkenyl groups in the composition} Ratio is in the range of 0.1 to 5.0; (C) photoactive type platinum complex curing catalyst, and (D) thermally conductive filler, wherein the composition has 30 Pa at 25 ° C. s to 800Pa. The viscosity of s, measured by a Malcom viscometer at 10 rpm. According to the present invention, it is possible to provide a composition which has high shape maintenance, low hardness, and can be stored at room temperature. |
