Smooth-Cast 321
Product Code:SOP3215G
Ultra-low viscosity casting resin that yield virtually bubble-free castings. A sister product to the popular Smooth-Cast 300 Series of bright white plastics, but easier to color using SO-Strong or Ignite color tints. Easy to mix and pour. Readily accepts pigments and fillers (such as URE-FIL 3 and URE-FIL 7). Fully cured castings are tough, durable, machinable and paintable. They resist moisture and mild solvents. Applications include reproducing small to medium size sculptures, making prototype models, special effect props, decorative jewelry and taxidermy (bones, antlers, teeth etc...). A release agent (Universal Mold Release or Ease Release 200) is necessary to facilitate demolding when casting into or over most surfaces.
