Used as an intermediate in the production of high-performance polymers, especially in the synthesis of specialty polyesters and copolyesters. It contributes to improving flexibility, thermal stability, and transparency in polymer formulations. Commonly applied in the development of optical films, engineering plastics, and resins for electronic and automotive industries. Also utilized in the preparation of UV-curable coatings and adhesives due to its reactive hydroxyl groups. Its bifunctional nature allows for cross-linking, enhancing mechanical and chemical resistance properties in final products.
