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.
Econ™ 80 is an economical Shore 80A urethane rubber suitable for a variety of mold making and industrial applications. It is a lower cost, faster cure alternative to our popular PMC™-780. Physical properties are lower vs. PMC™-780. This is a no odor system that features a 1A:1B mix ratio and a low viscosity for easy mixing and pouring. Working time is about 13 minutes at room temperature, handling time is 6 hours and rubber cures overnight. Econ™ 80 is translucent and easily colored with SO-Strong™ or Ignite™ colorants. Econ™ 80 is used to make short run molds for casting concrete and resins, concrete stamping pads, rubber mechanical parts, coating fabrics, pour-in-place gaskets for industrial equipment and burial vaults. Important: To minimize air bubbles in cured rubber, vacuum degassing is recommended.
