Smooth-On Smooth-Cast 300 Series Urethane Resin Kit Bright White
Smooth-On Smooth-Cast 300 Series Urethane Resin Kit Bright White
The Smooth-Cast 300 Series of liquid plastics are ultra-low viscosity casting 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 volume or 100A:90B by weight mix ratio. The differences between them are pot life and demold time.
These resins readily accept fillers (such as URE-FIL 3) and can be colored with SO-Strong or Ignite color tints (Smooth-Cast 325 series accepts pigments better than the Smooth Cast 300 series). Fully cured castings are tough, durable, machinable and paintable. They resist moisture and mild solvents. Applications for Smooth-Cast 300 Series Liquid Plastics include reproducing small to medium size sculptures, making prototype models, special effect props and decorative jewelry.
