Two-part room-temperature-vulcanizing silicones (RTV-2) are pourable, spreadable or kneadable formulations that vulcanize after mixing. There are two different types of crosslinking reactions: by condensation or by addition. Condensation curing requires an organotin catalyst and always releases byproducts. Addition curing requires a platinum catalyst and does not generate any byproduct.

Special RTV-2 silicone rubber grades can be flash vulcanized using UV light. The vulcanization time can be controlled by adjusting the UV intensity and exposure time.
