Used as a crosslinking agent in polymer formulations, particularly in coatings and adhesives to enhance thermal stability and mechanical strength. It improves curing efficiency in UV-curable systems and acts as a reactive diluent in epoxy and acrylate resins. Commonly applied in electronic encapsulants and printing inks due to its low volatility and good compatibility with various resin systems. Also functions as a plasticizer in specialty polymers where heat resistance and durability are required.
