Smooth-Cast ONYX® is a mercury-free urethane resin that cures quickly at room temperature to a deep black, solid plastic. ONYX® offers the convenience of a 1A:1B by volume mix ratio and has a very low viscosity, so it is easy to mix and pour. ONYX® has an ultimate shore hardness of 80D and offers higher physical properties and higher heat resistance vs. other general purpose resins. Advantages that ONYX® offers over other resins; 1) if you desire a black casting, adding color pigment is not necessary, 2) cured plastic is ultra-black and darker than competitive black resins, 3) cured ONYX® plastic can be polished and buffed to a high gloss shine and 4) ONYX® offers higher heat resistance vs. competitive black resins, 5) unlike other black resins, ONYX®does not contain mercury and 6) ONYX® is less expensive vs. other black resins. Applications include reproducing sculpture, making prototypes and potting / encapsulation. Because ONYX® is a fast curing resin and becomes hard quickly, it is also great for doing fast cold cast bronze, brass, copper, nickel/silver, etc. |
