Abstract
A thermally-conductive two-part addition-curable silicone composition including a first liquid and a second liquid and a method of producing the same. The first liquid includes a heat-treated mixture including an organopolysiloxane having two or more alkenyl groups and aluminum oxide having Naion content equal to or lower than 100 ppm, a platinum-group metal catalyst, and an ion-trapping agent of a cation-exchange type and/or a cation-and-anion-exchange type. The second liquid includes a heat-treated mixture including an organopolysiloxane having two or more alkenyl groups, an organohydrogenpolysiloxane having three or more SiH groups, aluminum oxide having Naion content equal to or lower than 100 ppm, and an organohydrogenpolysiloxane having two SiH groups.
