Product Description
Smooth-Cast™ 60D
The Smooth-Cast™ Semi-Rigid line of low-cost semi-rigid urethane casting resins cure quickly to semi-rigid plastics that offer exceptional strength and impact resistance.
New Formulations – New Look!
Smooth-Cast™ 60D is newly reformulated with a translucent white appearance and improved physical properties. All Smooth-Cast semi rigids are now mercury free and phthalate free. These plastics are easy-to-use (mix ratio is 1A:1B by volume) and have low viscosities for minimal bubble entrapment. Vibrant colors are possible by adding SO-Strong™, UVO™ or Ignite™ color pigments.
These semi-rigid plastics are good for making impact resistant prototypes, models, toys, props, climbing holds, etc.

TASK™ 4
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 73°F/23°C.
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.
