Smooth-Cast® 385 is a mineral filled urethane casting resin that is very hard and durable. When Parts A and B are mixed in proper proportion (1A:5B by weight), the material cures at room temperature with virtually no shrinkage. Smooth-Cast® 385 has high compressive and flexural strength. Fully cured castings are tough, machinable and paintable. Color effects are possible by adding pigment dispersions. They resist moisture and mild solvents.
Smooth-Cast® 385 is ideal for making industrial production parts, foundry patterns, vacuum forming molds, and some ceramic applications.
