Used as a crosslinker in silicone curing systems, especially in addition-cure silicones like RTV (room-temperature vulcanizing) rubbers. It reacts with vinyl-functional siloxanes in the presence of a platinum catalyst to form a durable, flexible network. This makes it ideal for sealants, encapsulants, and mold-making materials. Commonly found in electronics encapsulation due to its thermal stability and low shrinkage. Also used in coatings and release agents where controlled surface properties and durability are needed. Its hydrosilylation reactivity allows for precise control over cure speed and final material properties.
