Used primarily in the production of unsaturated polyester resins (UPR) for fiberglass-reinforced plastics, offering improved water resistance and mechanical strength. Commonly applied in corrosion-resistant tanks, pipes, and marine structures. Also utilized in the synthesis of high-performance coatings, resins, and plasticizers. Plays a role in producing specialty polymers like polyamides and polyesters with enhanced thermal and chemical stability. Employed in the manufacture of water-based alkyd resins for eco-friendly paints. Additionally, serves as a modifier in PET resin production to elevate glass transition temperature and reduce crystallization rate, beneficial for packaging and engineering plastics.
