PlatSil 73-20 -Platinum Silicone-

Polytek PlatSil Silicone was a revolution in the market when it was introduced more than 15 years ago. It has been imitated numerous times but never equaled in quality.

PlatSil Gel 73-20 is an easy-to-mix, two-part, 1A:1B, bi-component platinum silicone that cures extremely reliably in a rubber of hardness Shore:A22.

The translucent, bluish nature of the cured silica makes it a good choice for molds that need to be cut after curing, as the model is visible and parting lines can be better determined. It is also very useful when making molds of complex parts to ensure that all hard-to-reach parts of the part have been filled with silicone. This is a silicone from casting, but can be thickened or thixotroped with PlatThix to be brushed on.

PRECAUTIONS:

Sulfur contamination (e.g., sulfur-based clay), amines, compounds from tin, cured polyester resin, some paints and some silicone rubbers can inhibit the surface cure of platinum-cured rubbers.
