Abstract

The present disclosure provides a two component releasable thermal gel that is useful in transferring heat from heat generating electronic devices, such as computer chips, to heat dissipating structures, such as heat spreaders and heat sinks. The two component releasable thermal gel is mixed before the point of application and facilitates catalytic cross-linking. The thermal gel includes a first component including a primary silicone oil, an inhibitor, a catalyst, and at least one thermally conductive filler, and a second component including a primary silicone oil, a cross linking silicone oil, and at least one thermally conductive filler, wherein the ratio of total content of Si—H groups to total content of vinyl groups in the thermal gel is between 0.03 to 10. The thermal gel is releasable from a substrate upon which the thermal gel is applied.
