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.

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. Shake or stir Part A before use. This is a 1A:10B mix ratio product that must be measured by weight.
