• Ultra-low viscosity casting resin with bright white color.

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 from Smooth-On) and can be colored with SO-Strong, UVO 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. Those interested in making roto cast pieces should refer to the Smooth-Cast 65D technical bulletin.
