IsoMold HRS 5130

IsoMold HRS 5130 is used to make molds of detailed masters that contain shallow undercuts. Because IsoMold HRS 5130 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 HRS 5130 are concrete formliners and to make molds for point-of-purchase displays; rapid prototypes; special effects; taxidermy; and sculpture reproductions. IsoMold HRS 5130 is a two-part polyurethane molding system. IsoMold HRS 5130 is mixed one-to-one by volume (or 100-to-108 by weight) and cures at room temperature. IsoMold HRS 5130 contains no fillers and cures to a firm (Shore A58 ± 2); medium amber rubber.
