Product description

  • CHARACTERISTICS R PRO 20 is a 1 1 silicone rubber by liquid addition with high tear resistance. Suitable for modeling and moldmaking, this silicone rubber is very versatile and ideal for making medium-hard molds (20 shore) which allow you to reproduce even the smallest details and undercuts.
  • HIGH PERFORMANCE R PRO 20 mold silicone faithfully copies even the smallest details allowing you to make 20% more castings than other silicone rubbers and the molds have no linear shrinkage. It is a very fluid rubber that guarantees easy mixing and does not need to be degassed with vacuum machines.
  • MOLDS PERFORMANCE The physical life of the mold depends on how it is used (cast materials, frequency, etc.). Casting abrasive materials such as concrete can quickly erode mold detail, while casting non-abrasive materials (wax) does not affect mold detail.
  • NOTE Sulfur-based modeling clay is NOT compatible and may inhibit the catalysis of R PRO rubbers.
