PlatSil® Gel-10 Silicone Rubber is a two-part, platinum-catalyzed, liquid silicone system that cures (RTV) to a milky white, Shore A10 rubber. This silicone is most often used to make prosthetic appliances (in conjunction with Smith's Theatrical Prosthetic Deadener or PlatSil® Deadener LV), for lifecasting and mold making.
