This tutorial shows how to make a one piece silicone mold out of a transparent silicone. The clarity of the rubber allows for easier cutting and demold.
SORTA-Clear™ 12 is a premium water white translucent silicone rubber (platinum catalyst) which cures at room temperature with negligible shrinkage. SORTA-Clear™ 12 cures in 12 hours with a final Shore hardness of 12A. SORTA-Clear™ 12 features exceptional tear and tensile strength. Rubber clarity is especially useful when extracting models via cutting.
SORTA-Clear™ 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 SILC Pig™ pigments.
