TASK™ Series
High Performance Casting Resins
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.
HIGHLIGHTS
TASK™ 2 and TASK™ 3
TASK™ 2 and TASK™ 3
Low viscosity, fast cure resins made especially for rapid prototyping. These plastics are bright white and were formulated as higher performing alternatives to our Smooth‑Cast™ 300 Series resins.
