The information I have for Aeropoxy shows a glass transition temperature of
198 degrees F with only a room temperature cure (over a period of time). It
goes on to say that slightly better results can even be had by adding high
temp cures. It appears that a high temp cure is not needed for Aeropoxy...

Hey Guys,
Its simple physical chemistry. FRP materials like fiberglass layups
have a property of softening at a specific temperature known as Tg.
Tg is sensitive to the particular temperature exposure history of that
piece of layup. If you heatsoak a part in an oven for a few hours at 175F
then the Tg will become about 175, up from the base Tg of Eglass/
Aeropoxy of about 150 or so (I dont have my ref materials here at work).
