I'm looking for a glue that would allow to seal a large glass window
(1 m2) to a metal box and to evacuate the inner volume to about 10-5
Torr. Such glue should hold against thermal expansion mismatch up to
bake-out temperature of 120 C. So far I tried TorrSeal (epoxy) that is
ok for vacuum properties but is too rigid and cracks when thermal
cycling. VacSeal (silicone resin) should be flexible enough but is too
thin to compensate for surface imperfections. Also moisture permeation
rate could be high. Thanks in advance for any other suggestion...

Cheers
