The Smooth-Cast™ 325, 326 & 327 ColorMatch™ Series 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 using So-Strong™ tints or Ignite™ color pigments. The ColorMatch™ Series offers the convenience of a 1A: 1B mix ratio by volume and has a very low viscosity. Demold times range from about 10 minutes to 2-4 hours (depending on product, mass and mold configuration). Note: Large mass castings will get very hot and shrink more, depending on mold configuration.
The ColorMatch™ Series also readily accept fillers (such as URE-FIL™ 3 from Smooth-On). Applications for the ColorMatch™ Series plastics include making pigmented prototype models or figures, special effect props, reproducing small to medium size sculptures, decorative jewelry, etc.
TASK™ 18 is a relatively low viscosity aluminum filled urethane casting resin that was developed specifically for making short run vacuum forming or thermoforming molds.
When Parts A and B are mixed in proper proportion, TASK™ 18 cures overnight at room temperature with negligible shrinkage to a very hard plastic that has a very high compressive and flexural strength. Cured TASK™ 18 can be polished, machined, drilled, painted, etc. TASK™ 18 is also used to make industrial production parts, prototype parts and tracing patterns.
