The Smooth Cast® 320 Series consists of new ultra-low viscosity/low cost casting resins that yield virtually bubble-free castings. Smooth Cast® 320 Series resins pigment better and are lower in cost. Applications for Smooth Cast® 320 Series resins include reproducing small to medium size sculptures, making prototype models, special effect props, decorative jewelry, etc. Easy to mix and pour, these resins offer the convenience of a one to one mix ratio (one Part A to one Part B by volume). Fully cured castings are tough, durable, machinable and paintable. They resist moisture and mild solvents.
