TASK 4 is a unique polyurethane casting resin that is very strong when cast in Ultra-Thin sections ranging from 0.03" to 0.50"(0.075cm to 1.27cm).
TASK 4 has a very low mixed viscosity, ensuring flawless pick-up of even the finest detail. Cured plastic exhibits very low shrinkage which is why this plastic has become a favorite of prototype and design professionals throughout the world. Pot life is 20 minutes and cure time is 16 hours at 73F/23C. Vibrant colors and color effects are possible by adding SO-Strong color tints. Fully cured models made from TASK 4 are tough, durable, machinable and paintable. They resist moisture and mild solvents. Applications for TASK 4 include making prototype and architectural models, model toys, durable miniatures, ultra-thin mechanical parts and special effect props.
