Isotec’s IsoMold CMR 8001 is a two component polyurethane molding system. IsoMold CMR 8001 is mixed one-to-one by volume and cures at room temperature. IsoMold CMR 8001 cures to a hard (shore A 80±2) rubber in 48 hours. IsoMold CMR 8001 is used to make molds of detailed masters that contain some undercuts. It has excellent release characteristics to make molds for concrete stamp pads, sculpture reproductions, special effects and point-of-purchase displays.
