Smooth-Cast 325 ColorMatch 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 or UVO colourants.
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 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 jewellery, etc.
