PlatSil® Gel-25 Silicone Rubber is a two-part, platinum-catalyzed, liquid silicone system that cures (RTV) to a milky white, Shore A25 rubber. This silicone is most often used to make prosthetic appliances (in conjunction with PlatSil® Deadener LV or Smith's Theatrical Prosthetic Deadener), for lifecasting and mold making.
