The Smooth-Cast™ 325, 326, and 327 ColorMatch™ Series plastics are polyurethane resins that were developed specifically for adding colour pigments and fillers to achieve true colour representation or filler effect. The ColorMatch™ Series is formulated “colour neutral”. Small amounts of pigment will yield accurate, vivid colours from cured castings using So-Strong™ tints UVO™ pigments or Ignite™ colour pigments. The ColorMatch™ Series offers the convenience of a 1A: 1B mix ratio by volume and has a very low viscosity. Demould times range from about 10 minutes to 2-4 hours (depending on product, mass and mould configuration). Note: Large mass castings will get very hot and shrink more, depending on mould configuration.
The ColorMatch™ Series also readily accept fillers (such as URE-FIL™ 3 from Smooth-On). Because of its neutral colour, Smooth-Cast™ 325 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. 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.
