PMC™-746 was developed to make molds for casting gypsum plasters. This product is well suited for use as a rubber case mold – especially large case molds where extra rigidity is required. Shore hardness is 60A. Because of its durability and moisture resistant properties PMC™-746 is also used by zoos and museums for a variety of mold-making, display and exhibit applications. It features a convenient mix ratio (2:1 by weight or volume), and contains no mercury.
Other applications include making plaster block molds, reproducing ornamental plaster (architectural restoration), pre-cast concrete molds, casting waxes, Smooth-On rigid polyurethanes and epoxies and also for making a variety of special effects for movies and theatre.
