Advantages and Disadvantages of RTV Silicone Rubber

Advantages
RTV?Silicone?Rubber has the best release properties of all the mold rubbers, which is especially an advantage when doing production casting of resins (polyurethane, polyester and epoxy). No release agent is required, so there is no post-production cleanup. Silicones also exhibit good chemical resistance and high temperature resistance (400°F / 205°C and higher). High temperature resistance makes silicone the only mold rubber suitable for casting low melt metals and alloys (e.g. zinc, tin, pewter, and Wood's metal). The combination of good release properties, chemical resistance and heat resistance makes silicone well-suited for production casting of resins.
Disadvantages
RTV Silicone Rubber are generally high in cost - especially platinum-cure. They are also sensitive to substances (sulfur clay for example) that may prevent the silicone from curing (referred to as cure inhibition). Silicones are usually very thick (high viscosity), and must be vacuum degassed prior to pouring to minimize bubble entrapment. If making a brush-on rubber mold, the curing time factor between coats is long (longer than urethanes or polysulfides, shorter than latex). Silicone components (A+B) must be mixed accurately by weight (scale required) or they will not work. Tin catalyst silicones will shrink somewhat and do not have a long shelf life.
Certain types of RTV release acetic acid during the curing process, and this can attack solder joints, causing the solder to detach from the copper wire.
