Not necessarily; maintaining heat can also mean having a good thermal  
capacity.

FWIW, at work we once potted a small PCB in some epoxy stuff. Before  
we did that we glued several tiny Pt100 temperature sensors to the  
components that produced the most heat. Those components got much  
hotter in the unpotted circuit.
So, while epoxy is probably not a good heat conductor, it's still  
better than air.
