Used primarily as a curing agent and crosslinking agent in epoxy resin systems, providing enhanced thermal stability and mechanical strength to coatings, adhesives, and composites. Its branched aliphatic structure contributes to lower viscosity formulations, improving workability and allowing for easier processing in industrial applications. Also utilized in the synthesis of specialty polyamides and polyureas where controlled reactivity and flexibility are required. Due to its mixture of isomers, it offers a balanced reactivity profile, making it suitable for ambient and heat-cured systems in automotive, aerospace, and electrical insulation industries.
