Non-Silicone Thermal Interface Material. Electrolube Heat Transfer Compound is recommended where the efficient and reliable thermal coupling of electrical and electronic components is required.HTC Heat Transfer Compound is a non silicone thermal interface material recommended where the efficient and reliable thermal coupling of electrical and electronic components is required or between any surface where thermal conductivity or heat dissipation is important. They should be applied to the base and mounting studs of diodes, transistors, thyristors, heat sinks, silicone rectifiers and semi-conductors, thermostats, power resistors and radiators. As with all thermal interface materials, we would always encourage stringent testing before selecting a material for your application.
