Smooth-Cast™ 300Q liquid plastic is a quick setting, ultra-low viscosity casting resin that yield castings that are bright white and virtually bubble free. Vacuum degassing is not necessary. It offer the convenience of a 1A:1B by volume or 100A:90B by weight mix ratio.
This resin readily accept fillers (such as URE-FIL™ 3 from Smooth-On) 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. It resists moisture and mild solvents. Applications for Smooth-Cast™ 300Q Liquid Plastics include reproducing small to medium size sculptures, casting into alginate molds, making prototype models, special effect props and decorative jewelry.
