Isocast RCR 732

IsoCast RCR 732 is used to make castings from rigid and flexible molds. Some of the most common uses of IsoCast RCR 732 are point-of-purchase displays; rapid prototypes; special effects; and sculpture reproductions. However; IsoCast RCR 732 can be used for any application that requires a lightweight; hard plastic. IsoCast RCR 732 is a two-part polyurethane casting system. IsoCast RCR 732 is mixed one-to-one by volume and cures at room temperature. IsoCast RCR 732 begins to gel in 2-2.5 minutes; and cures to a white color.
