Task 8 is a heat resistant polyurethane casting resin used to make prototype models and high impact solid castings. Task series plastics are a new generation of performance urethane casting resins that offer superior physical properties compared to general purpose casting resins. Task 8 resin features low viscosity (100 cps), high tensile & compressive strength, and exhibits high heat resistance, up to 263F/129C. Mix ratio is one to one by volume. Color: Off-White. Shore D Hardness is 80. TASK 8 is available in trial (2.2 lb.) sets and 2 gallon 16.5 lb.) sets.
