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.

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.
