Description
The Smooth-Cast 320 Series consists of ultra-low viscosity casting resins that yield virtually bubble-free off-white castings. The Smooth-Cast 320 resins are sister products to our popular Smooth-Cast™ 300 Series of bright white plastics, but are easier to color using SO-Strong or Ignite color tints. Smooth-Cast 320 series is easy to mix and pour, offering the convenience of a 1A:1B by volume or 100A : 90B by weight mix ratio.
The Smooth-Cast 320 Series resins readily accept pigments and fillers (such as URE-FIL 3, 5 and 7 from Smooth-On). Fully cured castings are tough, durable, machinable and paintable. They resist moisture and mild solvents. Applications for Smooth-Cast 320 Series resins include reproducing small to medium size sculptures, making prototype models, special effect props, decorative jewelry and taxidermy (bones, antlers, teeth etc.).
