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.
