Thermalcote™ Thermal Grease

Thermalcote (Part #: 249, 250G, 251G, 252G, and 253G)

Thermalcote™ is a superior silicone-based thermal joint compound uniquely developed to increase heat transfer to all heat sinks. Thermalcote’s thermal conductivity is more than 15 times that of air and more than 4 times the conductivity of typical silicone-based greases. It is non-toxic and extremely stable; it neither cakes nor runs between -40°C to 204°C.
