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. 

 Advantages of liquid silicone rubber for mold making

1.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).

2. Silicones also exhibit very good chemical resistance and high temperature esistance (400°F / 205°C and higher). High temperature resistance makes silicone the only mold rubber suitable for casting low melt metal alloys (i.e. tin, pewter, lead).

The combination of good release properties, chemical resistance and heat resistance makes silicone the best choice for production casting of resins.
