TASK® 21

High Performance Urethane Casting Resin

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.
