Used as a curing agent and crosslinking promoter in epoxy resin systems, enhancing thermal stability and mechanical strength of coatings and adhesives. Commonly applied in high-performance composites for aerospace and electronics due to its extended pot life and improved resistance to moisture and chemicals. Also utilized in polyurethane formulations as a chain extender to modify reactivity and improve final material durability. Its long aliphatic chain contributes to flexibility in cured networks, making it suitable for elastomers and sealants.
