  • MIX RATIO: 1A:1B BY VOLUME - Easy to use silicone rubber compound features a convenient one-to-one by volume mix ratio, no scale is necessary
  • SHORE A HARDNESS: 30 - This scale measures the hardness of flexible rubber molds. A 30A hardness is in the soft to medium soft range, between the flexibility of a rubber band and pencil eraser
  • POT LIFE: 30 MINUTES, CURE TIME: 6 HOURS - This product cures at room temperature with negligible shrinkage. Best to store at room temperature, see "For Best Results" section below
  • LOW VISCOSITY FOR EASY MIXING AND POURING - Great for making simple one- or two-piece block molds, no vacuum degassing is necessary
  • PERFECT FOR ART AND INDUSTRIAL APPLICATIONS - Often used for molds to reproduce sculptures and other prototypes, casting plaster, resins, and wax

 

Use this silicone mold making rubber for making perfect reproductions that capture intricate detail of original models. OOMOO 30 is easy to use silicone rubber compounds that feature convenient one-to-one by volume mix ratios (no scale necessary).
