Silicone Rubber for Medium Hardness Moulds R PRO Fast, Mould Making kit DIY, 100% Safe, Non Toxic, Liquid, with Platinum Catalyst, high Tear Resistance, 1:1 Mixing Ratio (2 kg)

✔️R PRO FAST: Rapid prototyping 1:1 silicone rubber (the workability time is 5 minutes while the hardening time is 30 minutes) which creates rigid molds (35 shore) that last a long time and are excellent for casting wax, plaster, resins, cement and other materials. ✔️HIGH PERFORMANCE: It faithfully copies even the smallest details allowing you to make 20% more castings than other silicone rubbers. ✔️HARDNESS: The catalysed rubber allows you to make very rigid molds (hardness 35 ShoreA) and very "elastic" with a high resistance to tearing. ✔️MOLD 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., Manufacturer: Reschimica
