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. Glenn Pelkey Maxtek Components Corp.
