Product Description
TASK™ 2
TASK™ 2 low viscosity, high performance casting resins offer superior physical and performance properties compared to our popular Smooth-Cast™ Series of general purpose casting resins. Vacuum degassing is not necessary and it offers the convenience of a 1A:1B by volume (115A:100B by weight) mix ratio.
TASK™ 2 is white. It has high tensile and flexural strength, as well as high flexural modulus. This plastic was formulated for a variety of industrial applications including pattern making and making prototype models. This resin is designed for casting in thicknesses up to ½” (1.27 cm). TASK™ Plastics are moderately priced and are available in trial kits, one-gallon, five-gallon, 55-gallon drum and totes.

PMC™-746
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.
