Current price $415.00

LiquaFast® ICE is Castaldo's ultra-fast-curing, transparent 0% shrinkage RTV silicone mold rubber, developed for rapid production of CAD-CAM, RP, and SLA models. This two-part system forms tough, long-lasting molds ready in as little as 30 minutes — perfect for same-day casting workflows. Its clarity allows visual inspection of models during pouring and curing, while low viscosity ensures bubble-free detail replication.

Note: Hazardous material — ground shipping only. Not eligible for air or international shipment.

Features

  • Super-fast cure — ready-to-use molds in as little as 30 minutes.
  • 0% shrinkage for precision-fit wax patterns and accurate castings.
  • Transparent silicone formula allows direct visual inspection while curing.
  • Extremely tough and tear-resistant — molds resist softening over time.
  • Low viscosity simplifies measuring, mixing, and pouring with fewer bubbles.
  • Recommended vacuum degassing for optimal clarity and mold strength.
  • Economical alternative to traditional silicone RTVs — lower cost per mold cycle.

What's Included

  • LiquaFast® ICE Part A (clear base)
  • LiquaFast® ICE Part B (clear catalyst)
  • Total net contents: 4 kilograms (8.8 lb); mix 1:1

Compatibility

  • Optimized for CAD-CAM, RP, and SLA resin models, including Solidscape® and similar materials.
  • Ideal for jewelers and model makers requiring fast turnaround and high detail fidelity.
  • Compatible with most casting waxes and resins. Use a barrier coat for sensitive materials if required.
  • Recommended for professional jewelry mold making, prototyping, and small-scale production.

Notes

  • For best results, vacuum-degas after mixing and again after pouring to remove air bubbles.
  • To accelerate curing, warm molds gently to 120°F (50°C). Avoid overheating above 150°F (65°C).
  • If no vacuum pump is available, brush or dip the model before pouring the full mold to minimize air entrapment.
  • Maintain even room temperature (above 65°F / 18°C) during curing. Avoid temperature fluctuations.
  • Store unopened containers in a cool, dry place away from sunlight. Shelf life: approximately 6 months.
  • Classified ORM-D: ground shipping only; not for air or international transport.
  • Use gloves and eye protection. Work in a well-ventilated area.
  • Read and follow all Castaldo SDS and label precautions before use.
  • Professional use only — designed for experienced casters and mold makers.
