No Heat - No Pressure - No Shrinkage - No Waiting !

Rapid Molds from Rapid Prototypes.
Finished Molds in as Little as 30 Minutes.
Ideal for all CAD-CAM, RP, SLA WAX and Resin Models.

New LiquaFast™ ICE from CASTALDO® is a transparent two–part 0% shrinkage RTV silicone molding rubber that cures very rapidly at normal room temperatures and cures even faster at slightly warmer temperatures.

That means that you can make a mold from your CAD CAM, RP and SLA models in the morning, shoot waxes 30 minutes later and cast them that afternoon. No more waiting.

New LiquaFast ICE makes strong, tough, tear-resistant permanent molds that last and last and do not become soft with age.

LiquaFast ICE works well with all RP types, including hard-to-mold Solidscape® designs. LiquaFast Ice’s low viscosity makes it easy to measure, mix and pour.

Normal cure time is only 60 – 90 minutes. Faster cure is possible at only 50˚ C. / 120˚ F.

LiquaFast ICE is economical, costing far less than traditional silicone RTV materials.
