SORTA-Clear 37 Silicone rubber is a premium water white translucent silicone rubber (platinum catalyst) which cures at room temperature with negligible shrinkage. Available in Shore 37A hardness, these rubbers feature high tensile and tear strength. Sorta-Clear 37 offers the convenience of a 1A:1B by volume mix ratio.

SORTA-Clear 37 silicone is 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 silicone pigments. Cured Sorta Clear silicone has very high tear and tensile strength with virtually no shrinkage. Sorta Clear silicones are food safe, and can be used for culinary applications including casting chocolate and other confections.

Sorta-Clear 37 is mixed 1A:1B by volume, offers a 25 minute pot life, and a 4 hour demold time. Sorta-Clear 37 is available in trial (2 lb.) and 2 Gallon (16 lb.) sets.
