Smooth-Cast ONYX™ is a mercury-free urethane resin that cures at room temperature to a deep black, solid plastic.
ONYX™ resins offer the convenience of a 1A:1B by volume mix ratio and have very low viscosities, so they are easy to mix and pour. ONYX™resins have an ultimate
Shore hardness of 80D. ONYX™ resins are available in 2 speeds.
ONYX™ FAST resin has a pot life of 2.5 minutes and a cure time of 10-15 minutes
ONYX™ SLOW has a pot life of 5 minutes and a cure time of 90 minutes
cured plastic is ultra-black and darker than competitive black resins
can be polished and buffed to a high gloss shine
offers higher heat resistance vs. competitive black resins
does not contain mercury
less expensive vs. other black resins.
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.
