Used primarily as a reactive diluent and crosslinking agent in epoxy resin systems, enhancing the mechanical strength and thermal stability of cured resins. It is especially effective in UV and electron beam-curable coatings, adhesives, and printing inks due to its high reactivity and low volatility. Its cycloaliphatic epoxy structure contributes to excellent weather resistance and low yellowing, making it suitable for outdoor applications and clear coatings. Commonly employed in electronic encapsulation and composite materials where high performance and durability are required.
