TASK® 9 Colormatch is a high performance urethane casting resin that features very high compressive strength and tensile strength. TASK® 9 is clear amber, which makes this plastic very easy to color using SO-Strong® or IGNITE® colorants. With a mix ratio of 1A:1B by volume, TASK® 9 is easy to use and a low mixed viscosity (300 cps) ensures minimal bubble entrapment. Pot life is 7 minutes and cure time is about 60 minutes (depending on mass).TASK® 9 is ideal for making impact resistant tooling, color accurate prototypes / models as well as durable reproductions. This resin is designed for casting in thicknesses up to ½” (1.27 cm).
