How long do you need to post cure and at what temperature?

Kind regards,

This varies by resin. Casting and laminating resins that can be post-cured usually include a recommended curing schedule.

Some are lower temp cures like 250 degrees F. Some go up to 350. The higher the temp the greater the stiffness / temperature stability usually.

If it doesn't say but you want to try... test a little bit at 180 degree for 4 hours and see how it turns out before using all of the resin.
