Used primarily as a crosslinking agent in the production of specialty polymers and resins. Its unique spirocyclic structure enables the formation of highly stable, three-dimensional networks, improving thermal and chemical resistance in coatings, adhesives, and composite materials. Commonly employed in radiation-curable systems, such as UV-curable inks and coatings, due to its ability to undergo efficient polymerization under low-energy conditions. Also utilized in the synthesis of hydrolytically stable polymers for medical devices and packaging films, where resistance to moisture and degradation is critical. Its low volatility and high reactivity make it suitable for environmentally friendly formulations with reduced emissions.
