Hello Rick
Your problem sounds like a different one from the one that Jim described.
I would guess that it is a little cool where you are working and that you did
not use any type of hot box or anything other than room temperature. If I am
right that Epoxy can cure for two weeks and not be cured. It must go through
the exothermal process or it will never cure. Also if you have a slight off
balance of mixture it can also cause problems. Mylar will bond until the
Epoxy is completely cured and then it will release very easy. I am only
offering helpful suggestions as we all have had trouble at one time or
another. And we can learn from all of our mistakes if we share the
information. Let me know if I am close on my guess. If you want any info. on
hot boxes I can send you a copy of an article that I wrote for RCSD. Also
another good source of technical data is available from West Systems
Technical Manual and Catalog.
I hope that this helps. Del
