Hi Ron:

We do have water clear polyurethane material called PC2000VS/G2000VS.
It has the following basic properties:
Shore D 78-82, Pot life: 4-6 minutes, De-mold time: 30-40 minutes
Glass transition: 160-170 F.
Complete technical data sheet is available on our web site at:

It is best to fill the mold under vacuum. If the vacuum system is not
available or the mold can not be vented properly, you can use a pressure
tank. The mold has to be pre-heated to 140 deg. F, and filled mold must
be cured at 140 deg. F as well. You should not use a mold release,
since it can create a frosty surface.

Best regards,
Michael Tsenter
