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 (4 kg)

R PRO 30 is a two-component liquid silicone rubber for addition, meaning that two components, a base and a catalyst, need to be mixed in order for it to catalyze. This rubber is odourless, yellow in color and suitable for professional but also amateur use, as it is easy and safe to use, given that it does not contain dangerous ingredients not even in the platinum catalyst, which is usually the most harmful part of the two components. With R PRO 30 silicone casting rubber it is possible to create hard molds that are even complex and rich in details, unlike resins or harder rubbers, in which the reproduction of the smallest details can be damaged and broken during the de-molding phase , or the one in which the model is extracted from its cast. R PRO 30 is a silicone rubber with Shore A 30, a high degree of hardness, but still soft and elastic. This rubber also has excellent dimensional stability, with a linear shrinkage of 0%. This means that over time the mold does not shrink, but maintains its normal dimensions, thus resisting aging and lasting over time.
