PlatSil® FS-10 (Fast-Setting) Silicone Rubber is a two-part, platinum-catalyzed, liquid silicone system that cures (RTV) to a milky white, Shore A10 rubber. This product offers a simple 1A:1B mix ratio (by weight or volume), a fast demold time of ~25 minutes, and a long pour time (~8 minutes) relative to its cure speed. This allows for fast turn-around of molds and parts with sufficient time to mix and pour. Heat can be used to further accelerate the cure.
This is a pourable rubber, but it can be easily thickened with PlatThix Liquid Thickener for brush-on application.
