IsoCast RCR 703 is a two-part polyurethane rigid casting system. It is mixed one-to-one by volume and cures at room temperature. IsoCast RCR 703 begins to gel in approximately 2 minutes and cures to a creamy white color. IsoCast RCR 703 is used to make castings from rigid and flexible molds. Some of the most common uses of IsoCast RCR 703 are point-of-purchase displays; rapid prototypes; special effects; taxidermy; and sculpture reproductions. However; IsoCast RCR 703 can be used for any application that requires lightweight; hard plastic.
