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).

Materials should be stored and used in a warm environment (73°F/23°C). These products have a limited shelf life and should be used as soon as possible. All liquid urethanes are moisture sensitive and will absorb atmospheric moisture. Mixing tools and containers should be clean and made of metal, glass or plastic. Mixing should be done in a well-ventilated area. Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk.

Because no two applications are quite the same, a small test application to determine suitability for your project is recommended if performance of this material is in question.

Release Agent Silicone rubber molds (Mold Max® Silicones) do not require a release agent. Applying a release agent, however, will prolong the life of the mold. A release agent is necessary to facilitate demolding when casting into urethane rubber molds. Use a release agent made specifically for mold making (Universal® Mold Release or Mann’s Ease Release®200 available from Smooth-On or your Smooth-On distributor). A liberal coat of release agent should be applied onto all surfaces that will contact the plastic.

Mixing - Shake or stir both Part A & Part B before using. After dispensing required amounts of Parts A and B into mixing container, mix thoroughly. Stir deliberately making sure that you scrape the sides and bottom of the mixing container several times. Be careful not to splash low viscosity material out of the container. Material will briefly turn cloudy during mixing. Continue mixing until material becomes clear again before pouring.

Vacuuming - TASK® 9 is low in viscosity and does not require vacuum degassing. If you choose to vacuum the material, subject mixture to 29 h.i.g. mercury in a vacuum chamber until mixture rises, breaks and falls. Allow for 3 to 4 times volume expansion in mixing container. Be aware of pot life so that material does not set up in mixing container.

Pressure Casting - Best results are obtained using a pressure casting technique. After pouring the mixed resin into the mold, the entire mold is placed in a pressure chamber and subjected to 60 PSI (4.2 kg/cm2) air pressure for 60 minutes.
