Product Description
SORTA-Clear™ 37
SORTA-Clear™ Series rubbers are premium water clear translucent silicone rubbers (platinum catalyst) which cure at room temperature with negligible shrinkage. SORTA-Clear™ 37 has Shore 37A hardness and features high tensile and tear strength. This product also offers the convenience of a 1A:1B by volume mix ratio.
SORTA-Clear™ silicones are ideal for making prototype, jewelry or other molds of any configuration where model visibility is important (i.e. extracting a model from the mold via cutting). Materials such as urethane, epoxy or polyester resins can then be cast into SORTA-Clear™ silicone without application of a release agent. Other materials such as wax and low melt metal alloys can also be cast into SORTA-Clear™. SORTA-Clear™ can be pigmented with SILC Pig™ silicone pigments.
SORTA Clear™ 37 silicone rubber is FOOD SAFE and can be used for culinary applications including casting chocolate and other confections.
Certified Skin Safe - Cured SORTA Clear™ 37 is skin safe and certified by an independent laboratory.

TASK™ 16
TASK™16 is a low odor, fast-setting Shore 80A/30D urethane that offers very high tear strength, impact resistance and wear resistance. TASK™16 is phthalate free, mercury free and MOCA free. Mixed one part A to two parts B by weight, TASK™16 pours easily. Working time is 6 minutes and handling time is 90 minutes at room temperature. Cured rubber has exceptional performance characteristics and dimensional stability. TASK™16 can be colored with SO‑Strong™ or Ignite™ colorants.
TASK™16 is 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. TASK™16 is also an excellent choice for rotocasting to create hollow semi-rigid castings.
IMPORTANT: Cured TASK™16 will inhibit the cure of liquid platinum silicone. You can not pour platinum silicone into cured TASK™16. Tin silicone must be used if you intend to pour silicone against cured TASK™16.
