Abstract
A form stable thermally conductive urethane material comprising of a urethane resin, a urethane curing agent and one or more thermally conductive fillers. It is useful in transferring thermal energy, for example, from an electonic component to a heat sink. The thermally conductive urethane material eliminates the problems of migration and adherence of conformal coatings associated with other thermally conductive materials. The thermal conductive urethane material may be formed with or without a support layer of glass cloth, plastic mesh or film or metal mesh or foil. If desired, the thermally conductive material may be electrically insulative.
