Econ™ 80 is an economical Shore 80A urethane rubber suitable for a variety of mold making and industrial applications. It is a lower cost, faster cure alternative to our popular PMC™-780. Physical properties are lower vs. PMC™-780. This is a no odor system that features a 1A:1B mix ratio and a low viscosity for easy mixing and pouring. Working time is about 13 minutes at room temperature, handling time is 6 hours and rubber cures overnight. Econ™ 80 is translucent and easily colored with SO-Strong™ or Ignite™ colorants. Econ™ 80 is used to make short run molds for casting concrete and resins, concrete stamping pads, rubber mechanical parts, coating fabrics, pour-in-place gaskets for industrial equipment and burial vaults. Important: To minimize air bubbles in cured rubber, vacuum degassing is recommended.

SORTA-Clear™ Series rubbers are premium water clear translucent silicone rubbers (platinum catalyst) which cure at room temperature with negligible shrinkage. This product requires a gram scale for measuring parts A + B. SORTA-Clear™ 40 comes in Shore 40A hardness and features high tensile and tear strength.
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™ 40 silicone rubber is FOOD SAFE and can be used for culinary applications including casting chocolate and other confections.
Certified Skin Safe - Cured SORTA Clear™ 40 is skin safe and certified by an independent laboratory.
