SORTA-Clear 18 is a premium water white translucent Food Grade silicone rubber (platinum catalyst) that cures at room temperature with negligible shrinkage. SORTA-Clear 18 has a Shore hardness of 18A and features exceptional tear and tensile strength. Rubber clarity is especially useful when extracting models via cutting. SORTA-Clear rubber 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 SILC Pig silicone pigments.

Although not usually necessary, a release agent will make demolding easier when casting into or over most surfaces. Ease Release 200 is a proven release agent for making molds with silicone rubber and for releasing new silicone from cured silicone.
