Used primarily as a reactive monomer in the production of polyimide and polyurethane materials, this compound contributes to high thermal stability and mechanical strength in advanced composites. Its cyanate ester functional groups undergo polymerization to form triazine ring structures, making it valuable in aerospace, microelectronics, and structural adhesives where performance at elevated temperatures is critical. It is also employed in coatings and encapsulants for electronic components due to its low dielectric constant and excellent moisture resistance.
