Used as a crosslinking agent in polymer chemistry, enhancing mechanical and thermal stability of resins. Commonly applied in epoxy curing, where it improves adhesion and chemical resistance in coatings and composites. Also utilized in the synthesis of dendrimers and functional nanomaterials due to its multi-amino functionality. Finds use in water treatment as a flocculant modifier and in personal care products as a stabilizer or viscosity enhancer. Its reactivity allows for surface modification of silica and other inorganic materials in hybrid material production.
