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
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.
