Silicone rubbers are two-component systems (base plus curative; A+B) available in a hardness range of very soft to medium. Silicones can be cured with either a platinum catalyst or a tin catalyst. They are available for making molds that are poured, brushed or sprayed on to a model and have performance characteristics that no other mold rubber has. Silicone rubber has the best release properties of all the mold rubbers, which is especially an advantage when doing production casting of resins (polyurethanes, polyesters and epoxy). No release agent is
required, so there is no post-production cleanup. Silicones also exhibit very good chemical resistance and high temperature resistance (400°F / 205°C and higher). High temperature resistance mmakes silicone the only mold rubber suitable for casting low mmelt metal alloys (i.e. tin, pewter, lead). The combination of good mrelease properties, chemical resistance and heat resistance makes msilicone the best choice for production casting of resins.
