It is a bi-component rubber (base + catalyst) that thanks to its low viscosity and high elasticity allows copying faithfully even the smallest details. Ideal to make molds of any type and size and is particularly suitable for making objects and creations in plaster, resins, wax, soap, and cement. Thanks to the special catalyst formula we managed to:

  • Reduce the setting (from 12 hours to 6 hours)
  • Eliminate the bad smells typical of the other catalyseurs.
  • Improve technical and mechanical performance (+ 15% of casting compared to all other commercially available condensation silicone rubbers)
  • Improve the aging resistance of the molds
