Grease & Epoxy
ThermalcoteTM
ThermalcoteTM is a superior thermal joint compound of ther-
mally 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. ThermalcoteTM conducts heat approximately
15 times better than air and more than 4 times better than
unloaded silicone grease. It is non-toxic, extremely stable,
and neither cakes or runs from -40° to 204°C (-40°F to 399°F).

PRODUCT INFORMATION
Thermalcote™ II was developed as the sensible alternative
to silicone-based thermal greases. ThermalcoteTM II employs
a highly conductive synthetic base fluid that enables the
finished product to exhibit the same thermal characteris-
tics as the silicone-based products.

Thermalcote™ II contains no silicone. The high lubricity of
the base oil permits efficient application to both semicon-
ductor case or heat sink, and it will effectively fill the micro-
scopic air gaps on the metal-to-metal mating surfaces. It is
non-toxic, extremely stable, and neither cakes or runs from
-40° to 200°C (-40°F to 392°F).
