SORTA-Clear® 40 is a premium water white translucent silicone rubber (platinum catalyst) that cures at room temperature with negligible shrinkage. SORTA-Clear® 40 has a Shore hardness of 40A 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.
In this example, a block mold of a figurine is created using Sorta Clear 40® silicone rubber.
Sorta Clear 40® silicone is poured over the original figurine in the mold box.
The silicone mold is removed from the box.
The silicone is cut and the original is removed.
The mold is banded together and Smooth Cast 300 resin is poured in.
The casting reflects all of the detail of the original.
