	Assuming you mean heat-conducting, RTV silicone is a good adhesive
for this sort of thing.  The important thermal resistance is not likely
to be the adhesive (its path length, the thickness of the glue, is short),
but rather the package of the IC.  While 'loaded' adhesives have better
conductivity (we've used copper powder/epoxy mixes here, for our
cryostat work), the plain ol' gunk from the tube is entirely adequate.
