IsoMold CMR 3001 is used to make molds of detailed masters that contain some undercuts. IsoMold CMR 3001 was specifically designed to be used with pigmented and non-pigmented concrete. It has excellent release characteristics and durability. IsoMold CMR 3001 is a two-part polyurethane molding system. IsoMold CMR 3001 is mixed one-to-one by volume and cures at room temperature. IsoMold CMR 3001 cures to a soft (Shore A30 ± 2); rubber.
