IsoMold UMR 611

IsoMold UMR 611 is a two-part polyurethane molding system. IsoMold UMR 611 is mixed one-to-one by volume (or 1.04-to-1.00 by weight) and cures at room temperature. IsoMold UMR 611 contains no fillers and cures to a firm (Shore A61 ± 2); medium amber rubber. IsoMold UMR 611 is used to make molds of detailed masters that contain shallow undercuts. Because IsoMold UMR 611 is clear; it is ideal for projects that require the master to be visible during molding and cutting. Some of the most common uses of IsoMold UMR 611 are concrete formliners and to make molds for point-of-purchase displays; rapid prototypes; special effects; taxidermy; and sculpture reproductions.
