PlatSil® 73-40 Silicone Rubber
PlatSil® 73-40 Silicone Rubber is a two-part, platinum-catalyzed, liquid silicone system that cures (RTV) to a yellow, Shore A40 rubber. Since PlatSil® 73-40 has no shrinkage upon curing and resists mold distortion due to casting, it is an ideal product where dimensional stability is required. This is a pourable rubber, but it can be easily thickened with PlatThix Liquid Thickener or Fumed Silica for brush-on application.
FOR INDUSTRIAL/PROFESSIONAL USE ONLY.
