2-part silicone rubber (RTV-2)
RTV-2 silicone rubbers are two-part pourable, spreadable or kneadable compositions that vulcanize when the curing agent component is added and form highly elastic silicone rubber. They are cured at room temperature (RTV = room-temperature vulcanizing). There are two ways of vulcanizing them: In condensation-curing, an organotin catalyst is usually used; alcohol is produced as a byproduct. Addition curing, on the other hand, uses a platinum catalyst and does not produce byproducts.
RTV-2 silicone rubber can be used as an encapsulant for Electronics
