Abstract
Provided is a thermal interface material containing a divinyl polydimethylsiloxane, a chain extender, a crosslinker, 80 volume-percent or more thermally conductive filler, treating agent composition, platinum hydrosilylation catalyst, and up to 0.2 weight-percent hydrosilylation inhibitor; where the wherein weight-percent values are relative to thermal interface material composition weight, volume-percent values are relative to thermal interface material composition volume, the molar ratio of silyl hydride groups to vinyl groups in the thermal interface material composition is 0.4 or more and at the same time is 1.0 or less, and the molar ratio of silyl hydride functionality from the chain extender to silyl hydride functionality from the crosslinker is 13 or more and at the same time 70 or less.
