Used as a crosslinking agent in silicone rubber formulations, enhancing thermal stability and mechanical strength. Commonly applied in high-performance sealants and encapsulants for electronics due to its ability to form durable, heat-resistant networks. Also utilized in specialty coatings where resistance to environmental degradation is required. Its vinyl and siloxane groups enable efficient curing via hydrosilylation reactions, making it valuable in addition-cure silicone systems.
