Hello! Can i use vacuum degassing for removing all bubbles out of Water Clear Polyurethane Casting Resin or do a need to use a Pressure Pot to Cast in ?

Is it to fast cure time for Water Clear Polyurethane Casting Resin for using vacuum?

I think the vacuum degassing should work ok.

I use a water clear polyurethane that has a 15 minute pot life although I do not degas this one. It seems quite thin and should degas within a minute or two in a chamber.


Isn't the Water Clear Polyurethane pot-life 5 min?

The one I use is 15 minutes.
