TASK21 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. TASK21 has no odor and is easy to process. Mix ratio is 2A:1B by weight or volume. Pot life is 6 minutes and handling strength is reached in 60 minutes at room temperature (depending on mass and configuration).
TASK21 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 TASK21 include rapid prototyping, casting strong and highly detailed models, making holding / assembly fixtures, figurines and decorative castings.
TASK21 cannot be cast into platinum silicone molds . TASK21 may be cast into tin-cure silicone or urethane rubber molds (using a release agent).
