Anyone know of a slower curring resin than 3 minutes.

if you make a "bad" mixture (not enough hardener in the mix), it cures more slowly. This may effect the resin quality, though. Check with your chemist : he may have additives that slow down the curing process.

Why must it be more slowly ?

There are several "slow cure" resins out there... i use one (clear) for doing my water... look for URATHANE based resins rather than Poly-based resins.... it is still relatively quick though... instead of 3-4 minutes, you now will have 6-10 minutes.

Also, ALL resins cure themacally... they generate (and require!) heat to cure... so in colder weather (or in a cool place) they will cure more slowly.... but this may not be practical for you. If nothing else, try doing a pour with a small fan blowing on the cast unit... don't know if it will extend time THAT much, but ya never know!
