There is a common knowledge that heat will accelerate the hardening process of epoxy. Until now I have only been using heat from above. This has resulted in better builds. Anyhow, I haven’t been satisfied with the time not being THAT short. So I decided to add heat from underneath. This is a tricky bit since I’m using vacuum bagging. If using pneumatic presse one doesn’t have to take in considering sealing any air leakage…so to speak.
One simple way is to use silicone heat mat.
