Thermalcote™ is a superior thermal-joint compound of thermally-loaded silicone-based grease for use with all heat sinks. It improves the transfer of thermal energy across the metal-to-metal interfaces between the transistor or rectifier case and the heat sink. Thermalcote™ conducts heat approximately 15 times better than air and more than four times better than unloaded silicone grease. Opaque white in color, it is non-toxic, extremely stable, and neither cakes nor runs from –40° to 204°C (–40 to 399°F).
