TASK® Series

High Performance Casting Resins

TASK® Series

Smooth-On's specialty line of performance urethane casting resins that offer superior physical properties compared to our popular Smooth-Cast® line of general purpose casting resins. TASK® plastics feature convenient mix ratios by volume (pbv) or weight (pbw), low viscosities, high tensile and flexural strength, as well as high flexural modulus. Some have specific performance characteristics such as flame resistance, high temperature resistance, and very high impact resistance.
