Smooth-Cast 325 plastics are urethane resins specifically developed for adding color pigments and fillers to achieve true color representation or filler effect.

The ColorMatch Series is formulated “color neutral” - ideal for creating marble and wood grain casting effects, or duplicating the look of real metal by adding bronze, brass, or other metal powder. Small amounts of pigment will yield accurate, vivid colors in cured castings.

This easy-to-use plastic compound features a 1A: 1B mix ratio by volume (one part A to one part B by volume), has a very low viscosity, and vacuum degassing is not necessary. The differences between them are pot life and demold time.Fully cured castings are tough, durable, machine compatible, and paintable. They resist moisture and mild solvents.

Applications for Smooth-Cast Liquid Plastics include reproducing small to medium size sculptures, cold cast bronze castings, making pigmented prototype models or figures, roto cast pieces, special effect props, decorative jewelry, and more!

Net weight 32 oz. (909 grams). Demold times range from about 10 minutes to 2-4 hours (depending on product, mass and mold configuration).
