Used as a high-performance crosslinking agent in polyurethane systems, particularly in coatings, adhesives, and elastomers where exceptional thermal stability and chemical resistance are required. Its rigid molecular structure enhances the mechanical properties and durability of the final product. Commonly applied in aerospace, automotive, and industrial coatings due to its ability to form dense, crosslinked networks that improve hardness and abrasion resistance. Also utilized in specialty sealants where long-term environmental stability is critical.
