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. The silicone is safe to use at home. It is non-hazardous, non-poisonous and non-flammable.

The two-part compound produces a translucent silicone mold with 0% shrinkage; the semi-see-through material makes it easier to cut the finished mould because the model can be seen within.

Liquafast makes strong, tough, tear-resistant permanent moulds that last and do not become soft with age. This material works well with all RP types, including hard-to-mould designs as well as CAD/CAM and resin models..

The low viscosity of LiquaFast ICE makes the compound easy to measure, mix and pour; mix ratio is 1:1.

Normal cure time is only 60 – 90 minutes. Faster cure is possible at only 50˚ C.  That means that you can make a mould in the morning, shoot waxes 30 minutes later and cast them that afternoon. No more waiting.

Imported from USA-based Castaldo® - known throughout the jewellery industry for manufacturing the best jewellery moulding rubber for more than 40 years.
