SORTA-Clear® Series rubbers are premium water white translucent silicone rubbers (platinum catalyst) which cure at room temperature with negligible shrinkage. Available in Shore 18A, 37A and 40A hardness, these rubbers feature high tensile and tear strength. Sorta Clear® 37 offers the convenience of a 1A:1B by volume mix ratio. The 18A and 40A products require a gram scale for measuring parts A + B.

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.
