R PRO 20 - Silicone rubber 1:1 for medium hardness moulds, making kit for DIY

FOR PROFESSIONAL USE

R PRO 20 is a 1:1 addition silicone rubber with high resistance to tearing. 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.

✔️HARDNESS: The catalysed rubber allows you to make soft (hardness 20 ShoreA) and very elastic molds with a high resistance to tearing, the processing time is 45 minutes while the hardening time is 3 hours

✔️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.
