Abstract
The present invention provides a novel screen printable thermosetting composition for forming thermally conductive interface and a method of using the same. The composition is used to promote the transfer of heat from a source of heat such as an electronic device to a heat dissipation device such as a heat sink. The composition comprises by weight from about 35% to about 75% of a thermal curing vinyl terminated siloxane material, from about 0.005% to about 5% catalyst, from about 10% to about 30% hydrocarbon solvent and from about 20% to about 70% conductive filler.
