LiquaFast® ICE is Castaldo's fastest-curing 0% shrinkage RTV silicone mold rubber, specially designed for CAD-CAM, RP, and SLA models. This transparent two-part system produces strong, tear-resistant molds ready to use in as little as 30 minutes—ideal for rapid prototype workflows and short-run jewelry production. Low viscosity makes it easy to measure, mix, pour, and degas, even without vacuum equipment.
Features
- Cures in as little as 30 minutes at room temperature.
- 0% shrinkage for precise pattern reproduction.
- Transparent silicone allows visual inspection of masters during pouring and cure.
- Tough, durable, and tear-resistant molds that do not soften with age.
- Low viscosity ensures easy mixing, pouring, and bubble-free results.
- Compatible with most CAD-CAM and RP resins, including Solidscape® wax models.
- Economical alternative to traditional RTV materials—faster throughput with less downtime.
