Why is my resin still bendy?
Short Cure Time
In most cases, the reason you have resin that bends is due to the fact that the resin needs more time to cure. After 24 hours, ArtResin will be at a 95% solidity rate. If you attempt to curve or move the resin before that 24 hour mark, the resin will likely bend.
What happens if you add too much hardener to resin?
Too much hardener makes paint brittle. Adhesion, on the other hand, is a much bigger problem. If you mix too much epoxy hardener, this will just leave you with a sticky uncured hardener. Modern paint formulas are based on “flash times” chemical reactions between layers.
Why does resin take longer to cure?
The ideal room temperature for mixing ArtResin epoxy resin is between 75 and 85 degrees F or 24 - 30 degrees C. If it's colder than that, the resin will be thicker and harder to mix, will have more bubbles and will take longer to cure until it's dry to the touch.

Signs that your resin print is overcured
- Yellowing of prints: If you notice that your prints are starting to yellow or get discoloured, then you've exceeded the necessary curing time.
- Brittleness: A brittle resin print is a sign that you may have left the print in the curing station for too long.
What happens if you over cure resin?
Prints become brittle when over cured, and their impact resistance will weaken over time. The structural integrity of prints is definitely compromised when the curing process is pushed beyond normal or acceptable limits. So, in short yes: Resin parts can be over cured if exposed to UV light for too long.
