Used as a crosslinking agent in polymer chemistry, particularly in the development of epoxy resins and polyurethanes. Its structure contains multiple amine and hydroxyl groups, enabling it to enhance mechanical strength, thermal stability, and chemical resistance of cured resin systems. Commonly applied in high-performance coatings, adhesives, and composite materials where durability under harsh environments is required. Also utilized in the synthesis of functional materials for water treatment due to its ability to chelate metal ions. Its multi-armed structure with terminal hydroxyl groups improves flexibility and compatibility with various resin matrices.
