Abstract
The present invention provides a novel UV curable 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 UV curable acrylate material, from about 0.5% to about 15% catalyst, from about 10% to about 30% hydrocarbon solvent and from about 20% to about 70% conductive filler.
