Smooth-Cast® ColorMatch® 326

About
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®, UVO® or Ignite® colorants. 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). 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. 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.&&
