Platsil 7325



PlatSil® 73-Series RTV Silicone Rubbers are two-component, high strength, flexible, mold compounds. Molds made with 73-Series Silicones are excellent for casting many materials including polyester, epoxy and polyurethane resins.

The 73-Series Silicones are addition-cure, platinum-catalyzed systems, and offer advantages over tin-catalyzed systems in certain applications, because on curing they don’t shrink, they don’t produce alcohol (which can inhibit urethane castings), and their cure can be heat accelerated.
