Used as a curing agent for epoxy resins, providing excellent thermal and chemical resistance in coatings, adhesives, and composites. Its aliphatic structure contributes to improved UV stability and reduced yellowing compared to aromatic amines. Commonly employed in high-performance industrial applications such as electrical insulation, automotive components, and aerospace materials due to its mechanical strength and durability. Also utilized in the synthesis of polyurethanes and specialty polymers where controlled rigidity and flexibility are required.
