Used primarily as a crosslinking agent in the production of unsaturated polyester resins, enhancing thermal and chemical resistance of the final product. Commonly applied in the manufacturing of fiberglass-reinforced plastics for automotive and marine components. Also utilized in the formulation of adhesives and sealants where improved durability and moisture resistance are required. Acts as a reactive diluent in resin systems, reducing viscosity without compromising performance. Employed in some specialty coatings and electrical insulation materials due to its ability to form stable, rigid polymer networks.
