Product Description
TASK™ 18
TASK™ 18 is a relatively low viscosity aluminum filled urethane casting resin that was developed specifically for making short run vacuum forming or thermoforming 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.
XTC-3D™
XTC-3D™ is a protective coating for smoothing and finishing 3D printed parts. Two liquids are mixed together and brushed onto any 3D print. Coating self-levels and wets out uniformly without leaving brush strokes. Working time is 10 minutes and cure time is about 4 hours (depending on mass and temperature). XTC-3D™ cures to a hard, impact resistant coating that can be sanded, primed and painted. Adding colors and metal effects is easy.
