Used primarily as a crosslinking agent in the formulation of silicone elastomers and sealants, enhancing thermal stability and mechanical strength. It plays a key role in moisture-curable silicone systems, where it contributes to the formation of durable, flexible networks. Also employed in specialty coatings and adhesives requiring high performance under extreme conditions. Its unique spirocyclic structure supports low volatility and improved hydrolytic stability, making it suitable for long-life applications in automotive, aerospace, and construction industries.
