IsoCast RCR 732 (Formerly PAK Mark 2) 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.
