Very nice to hear, but all my other masters have been cast previously with tin, so it would be hard to add this. Nevertheless, this is VERY good news and it's nice to know it's available if ever I need it.

Smooth-On announces:

Sorta-Clear 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.
