IsoMold CMR 7001

IsoMold CMR 7001 is a two-part polyurethane molding system that is mixed one-to-one by volume and cures at room temperature. IsoMold CMR 7001 contains no fillers and cures to a firm Shore A 70 ± 2 within 48 hours at 23°C. IsoMold CMR 7001 is used to make molds of detailed masters that contain no or shallow undercuts. It is specifically designed for use in concrete casting applications. It has excellent release from pigmented or unpigmented concrete.
