Re: Recommended Epoxy System?

If you go to vacuum infusion using the PTM&W (2712) epoxy, the Tg can be raised to 212 degrees F. But that requires slow post curing cycles. That means raising the temp 10-20 degrees in at least 2 hour cycle periods. Every time you take the plane out of the hanger, if the temp is above the initial curing temp, the Tg will be raised, as long as the new temp is higher than the previous time. Unfortunately, if the plane is exposed to above Tg temp at any time, the plane is subjected to epoxy delinking and plane sag.
Each epoxy has a different ultimate Tg.
