PlatSil 7315 Silicone Rubber is a two-part, platinum-catalyzed, liquid silicone system that cures (RTV) to a white translucent, Shore A15 rubber. The transparent nature of the cured rubber makes it a good option for molds that need to be cut after cured – because the model is visible, parting lines can be better determined. It is also very useful when casting intricate parts to ensure that the entire mold cavity has been filled with casting material. This is a pourable rubber, but it can be easily thickened with PlatThix Liquid Thickener or Fumed Silica for brush-on application.
