TASK™ Series High Performance Casting Resins
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.
Task 4
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.
Task 13 & 14
Semi-Rigid Black Casting Resin: 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.
For Best Results… Do not cast TASK™ 13 or TASK™ 14 into platinum cure (addition cure) silicone molds.
Task 16
Tough 80A/30D Semi-Rigid Urethane: TASK™ 16 offers very high tear strength, impact resistance and wear resistance. Suitable for making fast mechanical parts, gaskets, wheels and pulleys, 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.
