Used as a crosslinking agent in silicone-based materials to enhance thermal stability and mechanical strength. Commonly applied in high-performance sealants and encapsulants for electronics, where resistance to heat and UV degradation is critical. Also functions as a photostabilizer in specialty coatings, improving long-term durability under intense sunlight. Its unique rigid vinyl structure supports efficient energy transfer in optoelectronic applications, making it suitable for use in certain OLED and sensor technologies.
