Casting PR and pressure pot?

[hanau]

For the ones that use a pressure pot to cast PR how long do you normally leave it under pressure?

I leave it in over night... PR takes longer to cure under pressure for some reason...

I'll leave my PR castings under pressure for overnight, and will try to get it close to 24 hours if possible. Sometimes the castings are pretty sticky to the touch when they come out, so I give them more time after demolding to harden.

You know i have noticed that also.

3 or 4 hours. No need after that. Bubbles are gone they are gone. Warm the resin before casting and you really do not need pressure.
