Used as a crosslinking agent in coatings and adhesives to improve durability, chemical resistance, and mechanical strength. Enhances flexibility and adhesion in polyurethane and epoxy systems. Commonly applied in industrial coatings, automotive finishes, and printing inks. Also serves as a reactive diluent and modifier in resin formulations to reduce viscosity without compromising performance. Its hydroxyl groups enable efficient curing under various conditions, making it suitable for UV-curable and water-based systems.
