PlatSil® 73-25 Silicone Rubber is a two-part, platinum-catalyzed, liquid silicone system that cures (RTV) to a green, Shore A25 rubber. This is a pourable rubber, but it can be easily thickened with PlatThix Liquid Thickener or Fumed Silica for brush-on application. The yellow colored Part A and green colored Part B make it easy to see when mixing is complete. A uniform, light, lime-green color means you’re good to go!
FOR INDUSTRIAL/PROFESSIONAL USE ONLY.
