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.
Thermalcote is avaliable in a 28 g (1 oz) and 57 g (2 oz) tube as well as a 0.45 kg (1 lb) can.
