More info
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), Smooth-Cast™ 385 cures at room temperature with virtually no shrinkage. This rigid urethane casting resin has high compressive and flexural strength. Fully cured castings are tough, machinable and paintable.
