| Smooth-Cast™ Colormatch™ For True Color Representation |
 Smooth-Cast™ Colormatch™ For True Color Representation |
Smooth-Cast™ ColorMatch™ plastics are fast-cast resins that were developed specifically for adding color pigments and fillers to achieve true color representation or filler effect. The ColorMatch™ Series is formulated "color neutral". Small amounts of pigment will yield accurate, vivid colors from cured castings (use of Smooth-On pigments is highly recommended). Because of its neutral color, the ColorMatch™ Series is ideal for creating marble and wood grain casting effects, or duplicating the look of real metal by adding bronze, brass or other metal powder (see Smooth-On technical bulletin for metal cold casting). - Smooth-Cast™ 325 ColorMatch™ - 10 minute demold time

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 and offer higher physical properties and higher heat resistance vs. other general purpose resins. 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, while ONYX® SLOW has a pot life of 5 minutes and a cure time of 90 minutes.
Advantages that ONYX® resins offer 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 6) ONYX® is 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. |

| Shell Shock™ Brushable Liquid Plastic |
 Shell Shock™ Brushable Liquid Plastic |
Shell Shock™ FAST and Shell Shock™ SLOW are thixotropic plastics that self -thicken when mixed and can be brushed onto a variety of surfaces or into rubber molds. When Parts A and B are mixed in proper proportion (1A:4B by volume or 1A:5B by weight), material cures at room temperature with virtually no shrinkage to a hard, durable plastic that exhibits good compressive and flexural strength. Fully cured castings are rigid and can be sanded, primed and painted. Color effects are possible by adding SO-Strong Color Tints. Shell Shock™ is ideal for making fast, lightweight rigid molds for creating silicone appliances and effects (use as a replacement for gypsum molds). You can also brush a "gel coat" into a rubber mold and back it up with rigid foam, creating a highly detailed lightweight casting. This product can also be brushed onto foam as an impact resistant coating that can be sanded, primed and painted (minimum 3/8" thickness recommended). Shell Shock™ can also be used to make rigid support shells for brush on rubber molds. Shell Shock™ FAST working time is 3 minutes. Shell Shock™ SLOW working time is 8 minutes.

| Feather Lite™ Liquid Plastic - It Floats In Water! |
 Feather Lite™ Liquid Plastic - It Floats In Water! |
Feather Lite™ is a heavily filled low-density urethane casting resin. Cured plastic is lightweight (it floats in water!) and has a much lower density than other casting resins. Feather Lite™ features a convenient 1A:1B by volume mix ratio and mixes easily (pre-mixing of parts A & B is necessary). Cured plastic is strong and can be carved, machined, drilled, sanded, etc. Feather Lite™ can be pigmented with SO-Strong™ color tints prior to casting and finished castings can be painted. And because this product is low-density, it yields more plastic per pound/kg. than other casting resins, the cost per casting is low. Feather Lite™ can be used for a variety of art or industrial design related applications including reproducing sculpture, making fishing lures, prototype model making, casting doll heads and figures, and many more applications. - Feather Lite™ - 2 hour demold time
