Used as a crosslinking agent in radiation-curable coatings and inks, enhancing film hardness and chemical resistance. Employed in the synthesis of energetic binders for propellants due to its ability to form stable, strain-free polymer networks. Also utilized in specialty resins for electronics, where moisture resistance and thermal stability are critical. Its reactive chloromethyl groups allow for easy functionalization in polymer chemistry, making it valuable in developing high-performance polyethers and polyurethanes.
