Used as a multifunctional crosslinker in coatings and adhesives to enhance mechanical strength and chemical resistance. Its high hydroxyl functionality enables efficient curing with isocyanates or epoxies, making it suitable for high-performance polyurethane and epoxy resin systems. Applied in specialty inks and electronic encapsulants due to low viscosity and high reactivity. Also serves as a precursor in dendritic polymer architectures for drug delivery and nanomaterials, where controlled branching and surface functionality are critical.
