IsoMold UMR 711 is a two-part polyurethane molding system. IsoMold UMR 711 is mixed one-to-one by volume and cures at room temperature to a hard (shore A70±4); dark amber rubber. IsoMold UMR 711 is used to make molds of detailed masters that do not contain undercuts. Some of the most common uses of IsoMold UMR 711 are diaphragms; dust boots; gaskets; liners; flexible molds; foundry patterns; wear pads; and concrete stamp pads.
