Smooth-Cast™ ONYX™ Series

Smooth-Cast ONYX is a mercury-free urethane resin that cures quickly at room temperature to a deep black, solid plastic. ONYX offers a higher heat resistance, up to 250 °F/121 °C, and the cured plastic can be polished. Applications include reproducing sculpture, making prototypes and potting / encapsulation. Due to it’s quick cure time and hardness, ONYX FAST is a good choice for creating fast cold cast bronze, brass, copper, nickel/silver, etc. effects.
