TASK® 2 & TASK® 3 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 they offer the convenience of a 1A:1B by volume (120A:100B by weight) mix ratio. The difference between TASK® 2 & TASK® 3 is the pot life and demold time. TASK® 2 & TASK® 3 are white. They have high tensile and flexural strength, as well as high flexural modulus. These plastics were formulated for a variety of industrial applications including pattern making and making prototype models. These resins are 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. |
