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 and is easy to process. TASK® 21 features a low mixed viscosity of 500 cps and readily de-airs itself when cast into molds. SO-Strong® or IGNITE® colorants can be added for color and a variety of powder fillers can be added to alter performance or appearance characteristics. Applications for TASK® 21 include rapid prototyping, casting strong and highly detailed models, making holding / assembly fixtures, figurines and decorative castings. IMPORTANT - TASK® 21 can not be cast into platinum-cure silicone molds. We recommend casting TASK® 21 into tin-cure silicone or urethane rubber molds (using a release agent).
