PlatSil® Gel-10


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.

PlatSil® Gel-10 has been tested by an independent laboratory and was found to comply with 21 CFR 177.2600 (as published in the Code of Federal Regulations) for rubber articles intended for repeated use food contact surfaces when accurately measured, thoroughly mixed, and fully cured.
