PlatSil 73-20 Silicone Rubber is a two-part, platinum-catalyzed, liquid silicone system that cures (RTV) to a blue translucent, Shore A20 rubber. Compared to other silicones in the PlatSil 73-Series line, this option sets quickly with a demold time of 1 hour (at room temperature). The transparency of PlatSil 73-20 is useful for molds that need to be cut after cure – parting lines can be better determined because the model is visible. 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.
