Used primarily as a reactive diluent and crosslinking agent in polymer formulations, enhancing the flexibility and durability of resins. Commonly applied in the production of unsaturated polyester resins for composites, coatings, and electrical insulation materials. Its ability to participate in curing reactions improves thermal and chemical resistance of the final product. Also utilized in the synthesis of specialty plastics and as a modifier in elastomers to increase resistance to heat and aging.
