Polytek Silicone
"PlatSil® 73-29 Silicone Rubber is a two-part, platinum-catalyzed, liquid silicone system that cures (RTV) to a white, Shore A30 rubber. This is a pourable rubber, but it can be easily thickened with PlatThix Liquid Thickener or Fumed Silica for brush-on application."
Notes:
Contamination from sulfur (e.g., sulfur-based clay), amines, tin compounds, cured polyester resin, some paints and some silicone rubbers may inhibit surface cure of platinum-cured rubbers. This is a 1A:10B mix ratio product that must be measured by weight. For additional physical property specifications, refer to the Physical Properties Bulletin.
