Smooth-On's specialty line of performance urethane casting resins that offer superior physical properties compared to our popular Smooth-Cast® line of general purpose casting resins. TASK® plastics feature convenient mix ratios by volume (pbv) or weight (pbw), low viscosities, high tensile and flexural strength, as well as high flexural modulus. Some have specific performance characteristics such as flame resistance, high temperature resistance, and very high impact resistance.
Low viscosity, fast cure resins made especially for rapid prototyping. These plastics are bright white and were formulated as higher performing alternatives to our Smooth‑Cast® 300 Series resins.
A unique casting resin that is very strong when cast in Ultra-Thin sections ranging from 0.03” to 0.50” (0.075cm to 1.27cm). TASK® 4 exhibits very low shrinkage which is why this plastic has become a favorite of precision prototype and design professionals throughout the world.
Vacuum degassing is not necessary and they offer the convenience of a 1A:1B by volume. Differences between TASK® 5 and TASK® 6 are the pot life and demold time.
Low viscosity, fast set casting resin that meets UL 94 V‑O requirements for flame resistance. TASK® 7 does not contain mercury, TDI or MOCA.
Made specifically for prototyping / casting applications which require thermal resistance of up to 263°F/129°C. Heat curing this material is necessary to attain optimal heat resistance.
Features very high compressive strength and tensile strength. TASK® 9 is clear amber, which makes this plastic very easy to color using SO-Strong®, UVO® or IGNITE® colorants.
Semi-rigid plastic that is strong and very tough. Originally developed for high impact tooling, TASK® 11 also offers good abrasion and chemical resistance and is ideal for a variety of industrial applications. This product is suitable for some FDA/USDA applications - dry food contact only.
Semi-rigid urethane resin that offers extraordinary handling strength and impact resistance. Used for a variety of industrial applications including making prototype models, high impact parts and tools. CAUTION: NOT FOR HOME USE. THIS PRODUCT IS FOR INDUSTRIAL USE ONLY.
With a Shore value of 50D, these semi-rigid plastics are used for a variety of industrial applications including fast mold making, fast model duplication, prototyping, durable miniatures, black props and special effects, or making parts that are impact resistant.
Features a gradual cure profile, making it ideal for rotational casting applications (making hollow parts). TASK® 15 exhibits very high impact strength, even when cast in thin-wall sections.
TASK® 16 offers very high tear strength, impact resistance and wear resistance. Suitable for making fast mechanical parts, gaskets, wheels and pullies, impact resistant props, and archival master models. It is also used to make fast, wear resistant rubber molds for casting concrete or concrete stamping pads.
Relatively low viscosity aluminum filled urethane casting resin that was developed specifically for making short run vacuum forming molds with a very high compressive and flexural strength.
A performance urethane casting resin that has been described by many as having similar performance and mechanical characteristics to ABS plastic, with high compressive and flexural strength.
IMPORTANT - TASK® 21 can not be cast into platinum‑cure silicone molds.
