Steve,

Epoxy Technology Inc., Billerica MA, Tel. (508) 667-3805, (800) 227-2201
has a Conductive Epoxy, Type H20E, which is specified to have 16oz of shear
strength at .1"x.1 pad. It can be cured at 175 degrees C for 45 sec, or at
lower temperatures, but longer. 

Tra-Con, Bedford MA, Tel (800) TRA-CON1 has also a Conductive Epoxy, but I
have no specs. at hand.

I am not sure whether this is the type of 'adhesive' you meant. In any case
I hope it will help you.
