Used as a crosslinking agent in polymer chemistry, particularly in the modification of unsaturated polyester resins to improve thermal stability and mechanical strength. It also serves as a reactive diluent in radiation-curable coatings and inks, enhancing curing speed and film performance. Its bifunctional ester structure allows it to participate in esterification and transesterification reactions, making it useful in synthesizing specialty monomers and additives for adhesives and composites.
