Smooth-On - Mold Star 16

Mold Star 16

Cast production molds in 30 minutes that capture every surface detail

Platinum-cure silicone eliminates the cure inhibition problems that plague tin-cure rubbers. Mold Star 16 flows into fine surface details, then cures to a flexible Shore 16A hardness that releases cleanly from undercuts while maintaining dimensional accuracy. The six-minute pot life gives you enough time to pour complex molds without rushing, while the thirty-minute cure means you're demolding and casting within an hour of mixing.

This silicone stretches rather than tears when demolding intricate pieces, and the platinum cure chemistry ensures minimal shrinkage over years of use. Heat resistance to 450°F handles casting operations that would destroy ordinary mold materials, pour molten wax or low-temperature metal alloys directly into these molds. The cured rubber works equally well with resins, concrete, and gypsum, making it genuinely versatile for production work.

Mix equal parts A and B by volume or weight. The low viscosity means thorough mixing without incorporating excessive air, and the material self-levels to eliminate brush marks. Molds pull detailed texture from original models and reproduce that fidelity through hundreds of castings.
