Product description

  • FEATURES R PRO 20 is a 1 1 addition-cure liquid silicone rubber with high tear resistance. Suitable for modeling and mold making, this versatile silicone is ideal for creating medium-hardness molds (20 Shore) that reproduce even the smallest details and undercuts.
  • HIGH PERFORMANCE R PRO 20 silicone for molds faithfully reproduces fine details, allows up to 20% more castings compared to other silicones, and molds have no linear shrinkage. It is a very fluid rubber that ensures easy mixing and does not require vacuum degassing.
  • HARDNESS Once cured, this silicone produces soft molds (20 Shore A hardness) that are highly elastic and resistant to tearing. Working time 45 minutes Curing time 3 hours.
  • MOLD PERFORMANCE The physical lifespan of the mold depends on its use (casting materials, frequency, etc.). Casting abrasive materials such as concrete can quickly wear out mold details, while non-abrasive materials (such as wax) preserve them.
  • NOTE Sulfur-based plasticine is NOT compatible and may inhibit the curing of R PRO silicones.
