Used as a cross-linking agent in silicone curing systems, particularly in platinum-catalyzed addition-cure silicones. It enhances thermal stability and mechanical properties of silicone elastomers. Commonly applied in high-performance sealants, encapsulants, and coatings where durability at elevated temperatures is required. Also serves as a monomer in specialty silicon-based polymers for electronics and aerospace materials due to its ability to form stable, flexible networks.
