Used primarily as a crosslinking agent in polymer chemistry, especially in the production of unsaturated polyester resins. It enhances thermal stability and mechanical strength of the resulting polymers. Also employed in the synthesis of specialty resins and as a reactive diluent to reduce viscosity during resin processing. Its ability to participate in free radical polymerization makes it valuable in coatings, adhesives, and composite materials. Additionally, it serves as a chemical intermediate in the manufacture of high-performance plastics and elastomers.
