Description

This utility and modeling clay is designed for special effects and industrial design, offering superior structural integrity for manual hand-sculpting. It is non-meltable, ensuring no risk of liquefaction.

Applications

  • Building registration keys
  • Creating mold walls and parting shims
  • Plugging leaks

The Extra Soft version (9A) is tacky for better adhesion, while the Hard version (32A) allows for crisp, tooled edges. Its off-white color and non-toxic, odor-free formula make it suitable for classroom environments and long-term studio projects. It offers a smooth, buttery feel that holds detail well without requiring a melt-pour workflow.

Grades

  • Extra Soft: 9A Durometer, Tacky finish
  • Soft: 14A Durometer, Low Tack
  • Medium: 26A Durometer, Low Tack
  • Hard: 32A Durometer, Low Tack

Medium and Hard grades require warming to 46°C to reach a workable state, regaining firmness upon cooling.

Instructions

  • Extra Soft and Soft grades are optimized for use at room temperature (23°C). 
  • Medium and Hard grades should be warmed to 46°C to achieve a workable consistency; they will return to their original firmness upon cooling.

Smoothing

  • Use rakes for initial leveling.
  • For a glass-like finish, apply 99% Isopropyl Alcohol or Naphtha.
  • Citrus solvents work but may inhibit silicone curing.

Safety

  • Do not overheat the clay to avoid burns.
  • Store in airtight wrap away from UV to prevent oxidation.
  • Clean tools with alcohol or Naphtha, as the clay can stain fabrics.
