Product Overview
PMC™-746 urethane rubbers were developed to make molds for casting gypsum plasters. Like PMC™-744, 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 urethane rubbers are also used by zoos and museums for a variety of mold-making, display and exhibit applications. They feature a convenient mix ratio (2:1 by weight or volume), and contain 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.
What’s the Difference? The color of cured original PMC™-746 ranges from amber to blue from batch to batch due to variability in raw materials. Cured PMC™-746 Clear Amber is clear amber in color and will be the same color batch to batch.
