Smooth-Cast® 385

Mineral Filled Liquid Plastic

Smooth-Cast® 385 is a casting resin that is very hard and durable. The material cures at room temperature with virtually no shrinkage with high compressive and flexural strength characteristics. Fully cured castings are tough, machinable, paintable and resist moisture and mild solvents. Smooth-Cast® 385 is ideal for making industrial production parts, foundry patterns, vacuum forming molds, and some ceramic applications.
