IsoMold CMR 4001

IsoMold CMR 4001 is a two-part polyurethane molding system. IsoMold CMR 4001 is mixed one-to-one by volume and cures at room temperature. IsoMold CMR 4001 cures to a medium (Shore A 40 ± 2); gray rubber. IsoMold CMR 4001 is used to make molds of detailed masters that do not contain undercuts. IsoMold CMR 4001 physical properties make it ideal for making concrete patterns and formliners.
