Sorta-ClearŪ 18 - A NEW Softer High-Clarity Platinum Silicone

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.

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).

Resins (urethane, epoxy, etc.), wax and low melt metal alloys can also be cast into SORTA-Clear®. SORTA-Clear® can also be cast into platinum silicone (release agent required) or rigid molds for casting translucent prototype parts, etc. SORTA-Clear® can be pigmented with SILC Pig® silicone pigments.
