Smooth-Cast™ 325

Fast Set Colormatch Resin

The Smooth-Cast™ 325, 326 & 327 ColorMatch™ Series plastics are fast-cast 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 colors from cured castings using So-Strong™ tints 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 color, 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 (see Smooth-On technical bulletin for metal cold casting). 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.
