Used as a crosslinking agent in polymer chemistry, particularly in the synthesis of thermosetting resins and specialty coatings. Its trifunctional ester structure enables efficient network formation when reacted with nucleophiles or during free radical polymerization, enhancing thermal and mechanical stability of the resulting materials. Commonly applied in developing heat-resistant adhesives and encapsulants for electronic components due to its ability to form dense, chemically resistant polymer matrices. Also investigated as a reactive diluent in UV-curable systems, where it improves cure speed and final material hardness.
