Instructions

Important Notes

  • Weigh components using a gram scale for accuracy.
  • Not suitable for molds casting Crystal Clear™ or Clear Flex™ Series urethanes.
  • Conduct a small test application to ensure suitability.

Safety

  • Use in a well-ventilated area.
  • Wear safety glasses, long sleeves, and rubber gloves. Use vinyl gloves only.

Storage

  • Store at room temperature (23°C).
  • Warmer storage reduces shelf life.
  • Use products as soon as possible due to limited shelf life.

Applying a Sealer / Release Agent

  • May be inhibited by sulfur-based clays.
  • Test compatibility with the surface.
  • Use a barrier coat of clear acrylic lacquer if needed.
  • Ease Release™ 200 is recommended for easier demolding.

Measuring & Mixing

  • Pre-mix Part B thoroughly.
  • Mix parts A and B for 3 minutes, scraping sides and bottom.
  • Vacuum degassing is recommended.

Pouring / Curing / Post Curing

  • Pour mixture at the lowest point of the containment field.
  • Allow to cure overnight at room temperature before demolding.
  • Post cure for 4 hours at 65°C to eliminate residual moisture.

Thickening for Brush-on Application

  • Use THI-VEX™ for thickening.
  • Apply thin coats, allowing each to become tacky before the next.

Accelerating Cure Time

  • Accel-T™ can be used to accelerate cure time.
  • Note: This reduces the mold's library life.

Thinning

  • Silicone Thinner™ lowers viscosity and increases pot life.
  • Do not exceed 10% by weight of the total system.

Mold Performance & Storage

  • Mold life depends on usage and materials cast.
  • Clean molds with soap solution before storage.
  • Store assembled molds on a level surface in a cool, dry environment.
