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 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.

Those interested in making roto cast pieces should refer to the Smooth-Cast™ 65D technical bulletin.


  • Easy to measure and mix - 1:1 mix ratio by volume - no scale required
  • Low viscosity - captures excellent detail - no degassing necessary
  • Resin cures to a bright white finish

Excellent Customer service and fast delivery

The Team at Resin Craft have fantastic customer service and deliver at lightening speed. I also approached them a day after I'd purchased as it was Black Friday and they extended the discount to me. 5 *****'s! Would purchase again.

The product came well packaged and in excellent condition.
