Product Description
TASK™ 3
TASK™ 3 low viscosity, high performance casting resin offers 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™ 3 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.
