The Condensation Cure Silicone Rubber is suitable for making molds from materials that can prevent additive curing, such as bee wax, 3D prints and clay.

Processing instructions

  • Weigh components A and B carefully according to the mixing ratio (100:5).
  • Mix the components well (tip: use the two-cup mixing method).
  • Pour the silicone mass into the deepest part of the mold in a thin stream (do not pour over the piece itself to prevent air bubbles).
  • Now leave to cure for at least 24 hours.
  • For optimal properties, the mold can be post-treated in an oven (150°C).
