Used primarily in the production of polyurethane elastomers and coatings requiring high durability and resistance to heat and UV degradation. Its alicyclic structure contributes to improved light stability, making it ideal for outdoor applications such as protective coatings, industrial finishes, and automotive components. Also employed in specialty adhesives and sealants where enhanced weatherability and mechanical strength are required. Due to its bifunctional isocyanate groups, it effectively crosslinks with polyols to form rigid, chemically resistant networks.
