TASK® 18 is a relatively low viscosity aluminum filled urethane casting resin that was developed specifically for making short run vacuum forming molds. When Parts A and B are mixed in proper proportion, TASK® 18 cures overnight at room temperature with negligible shrinkage to a very hard plastic that has a very high compressive and flexural strength. Cured TASK® 18 can be polished, machined, drilled, painted, etc. TASK® 18 is also used to make industrial production parts, prototype parts and tracing patterns.
