MasterSil 415A, a high performance silicone elastomer, is highly transparent.

It cures at ambient temperatures to a flexible, rubbery solid when exposed to atmospheric moisture. It has a paste consistency and can be applied on vertical surfaces without sagging or running. It has an 8 to 12 min. set-up time at 75°F and can be used in temperatures ranging from 185 to 400°F. It can also serve a an electrical insulator with a dielectric strength of 500V/mil (1/8 in. thick test speciman). The materials resists moisture and weather, has a 30 Shore A hardness, elongation of 400% (at 75°F, and a tensile strength of 325 psi.
