he 1A:5B mix ratio version of PlatSil® 71-40 Silicone Rubber is no longer available - please consider the new PlatSil® 71-40 Silicone Rubber formulation, which features a 1A:10B mix ratio (described below).
NEW 1A:10B FORMULATION:
PlatSil® 71-40 Silicone Rubber is a two-part, platinum-catalyzed, liquid silicone system that cures (RTV) to a translucent, Shore A40 rubber. This is a pourable rubber, but it can be easily thickened with PlatThix Liquid Thickener or Fumed Silica for brush-on application.
DO NOT mix this new formulation with old PlatSil® 71-40 formulations.
