Smooth-On - Smooth-Cast 325 ColorMatch Liquid Plastic Compound

Smooth-Cast 325 ColorMatch Liquid Plastic Compound

Achieve museum-quality reproductions with color-neutral resin for true tones

1B mix ratio eliminates calculation errors during time-sensitive pours.

Seven to ten minute demold time keeps production moving without sacrificing working time. The 2.5 minute pot life provides enough margin to mix pigments or metal powders thoroughly and pour with control, then parts release quickly enough for efficient turnaround. Cured castings achieve 3,170 psi tensile strength, tough enough for functional prototypes and handles that see actual use, not just display pieces.

This formulation excels at cold cast metal effects where bronze, brass, or aluminum powder suspended in the resin creates convincing metallic surfaces, or marble and wood grain effects where pigment dispersion determines realism. Minimal .01 inch per inch shrinkage maintains dimensional accuracy for parts that need to fit together. Moisture and mild solvent resistance protects finished pieces during handling and light cleaning. The 32-ounce kit provides enough material for multiple small castings or one substantial piece.
