Liquid Silicone Rubber for Molds 1:1 R PRO 30, Non-toxic, Easy to Use, resistant to breakage, 30 shore, Compatible with epoxy resins, plaster, wax and other materials (500 gr)

✔️CHARACTERISTICS: R PRO 30 is a 1:1 silicone rubber by liquid addition with high resistance to tearing. Suitable for modeling and moldmaking, this silicone rubber is very versatile and ideal for making high hardness molds (30 shore) which allow you to reproduce even the smallest details. ✔️HIGH PERFORMANCE: R PRO 30 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 30 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.
