Polyurethane Casting Resin

The PUCast Series is a two-component polyurethane casting resin which exhibits good impact resistance and strength, ultra-low viscosity casting polyurethane resins that yield castings that are bright white and virtually bubble-free. Vacuum degassing is not necessary. They offer the convenience of a 1A:1B by weight mix ratio. The differences between them are pot life and demold time.

Fully cured castings are tough, durable, machinable and paintable. Applications for PUCast Series polyurethane casting resin include reproducing small to medium size sculptures, making prototype models, special effect props and decorative jewelry.
