SORTA-Clear® 18 is a premium water white translucent silicone rubber (platinum catalyst) that cures at room temperature with negligible shrinkage. A softer version of our popular SORTA-Clear® 40, this rubber has a Shore hardness of 18A and features exceptional tear and tensile strength. 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. Sorta Clear® 18 is also FOOD SAFE and can be used for culinary applications including casting chocolate and other confections |
