TASK™ 21

TASK 21 is a performance urethane casting resin that has been described by many as having similar performance and mechanical characteristics to ABS plastic, with high compressive and flexural strength. TASK 21 has no odor, is easy to process and features a low mixed viscosity of 500 cps so readily de-airs itself when cast into molds. Applications for TASK 21 include rapid prototyping, casting strong and highly detailed models, making holding / assembly fixtures, figurines and decorative castings.

NOTE: TASK 21 CAN NOT be cast into platinum silicone molds.
