Is this really a heat conductor? Seems to be not possible, but then

There is a version of "Stycast" that has thermal properties, and you
can
add silica powder to nearly any epoxy and increase its capacity to
pass heat a huge amount.

3M makes a thermally conductive glue for gluing heat sinks to
semiconductors. We used to use it at TEK.
It's a 2 part system,a glue and catalyst,like a cyanoacrylate and
accellerator.
