Can anyone recommend a compound that offers adhesion and thermal
conductivity between an IC and a thermal resistor?  The old compound
I'm replacing was gray and retained some elasticity (Roland JP-8). 
Another I've seen was white and had hardened completely (Octave Cat).
 Silicon grease has been suggested but doesn't seem to really cure
into a semisolid bond.  Thanks.

Greetings:

3M May make a product -- 3m.com -- Although I don't recall seeing any
that really have a setting characteristic to them, but I am sure they
exist.  They are usually a grease like coumpound and you use a clamp
or bracket to hold the parts togather.

An option is JB Weld, available at most automotive stores, Fleet Farm,
etc.  It is a metal filled epoxy polymere that is good to about 600
degrees.  I have used it to mount a steel plate on an aluminum oil pan
for a magnetic heater.  Works very well.  I am not sure if it is
electrically conductive -- I haven't tested it. Also it is pretty
permanent, but could be removed I suspect if you didn't use too much
to make the bond joint.

Peter

I've done some research and found a few products that meet my
requirements:

Loctite 384 (use with 7387 activator) -- acrylic, thermally
conductive, fast-curing, non-permanent adhesive

CHO-THERM 1641 (1 part)/1642 (2 part) -- silicone thermally conductive
adhesive, average cure time, non permanent

3M TC-2707/TC-2810 -- 2 part epoxy thermally conductive adhesive

I'd like to try the CHO-THERM, but I can't seem to find a source yet.
 I'll probably first try the Loctite since it seems to be more readily
available.  I hope this saves someone a couple of hours on Google.

Thanks,
Stephen
