Hi,

I have a question regarding curing epoxy to get the best results. The project is a hand layup of fiberglass 3 oz and I'm working with a room temperature curing epoxy with the following properties:
- Gel Time (@ 21C) 38 min
- Demold Time 24hr
- Deflection temp 53 C
- full cure at room temperature 7 days

I'm a lite confused about what is considered the

"

curing'' and 

"post-cure" period, when and how much heat to apply (and for how long).

Thanks

Alexandre

Not uncommon to find no post-cure data, but generally you should always be able to find a 'Tg' or 'HDT' value, which is the upper temperature limits of the resin. For most entry level epoxies this is around 60 degrees.

If you can't find any data at all, I would hazard a guess at it being around a 60 degree Tg, so you could do a post-cure of 60 degrees for 16 hours. Ideally you would ramp up to this temperature slowly, 0.5-1 degree per minute.
