Used as a curing agent in epoxy resin systems, enhancing mechanical strength and thermal stability. Its cycloaliphatic structure provides improved UV resistance and reduced viscosity in formulations, making it suitable for coatings, adhesives, and electrical encapsulation. The trans isomer offers faster reactivity and better symmetry compared to the cis form, leading to more consistent crosslinking. Also employed in specialty polymers where controlled rigidity and flexibility are required.
