Used as a high-performance plasticizer and crosslinking agent in polymer formulations, enhancing flexibility and thermal stability of polyurethanes and epoxy resins. Commonly applied in coatings, adhesives, and sealants where improved durability and resistance to heat and hydrolysis are required. Also functions as a chain extender in specialty elastomers, contributing to mechanical strength and long-term aging resistance. Its aromatic and ether-based structure supports good solubility in organic matrices and promotes adhesion to various substrates.
