There is a guy at a company called "Master Bond" named Dr. Brenner. He is
not a sales type and is pretty smart. Another good company is "cotronics

> Hello Technetters,
>
>      Like everyone else, we are in search of the perfect epoxy or
> similar material.  Our use is in backfilling a Nickle plated cavity,
> approximately 1.0 x 0.5 inches.  Unfortunately, results so far have
> shown poor adhesion to the Nickle and material shrinkage that has
> resulted in gaps at the interface.
>      We certainly don't want any trade secrets, but does anyone have a
> recommendation for solving this situation?  We've tried roughing up the
> surface for adhesion and a couple of low temperature cure epoxies with
> no luck.  We're now thinking about Silicones.
>      One other piece of this puzzel is the device must survive 1000
> temperature cycles between -40 and +85 C.
>
>      Thanks in advance for any input.
