Isophorone Diamine (IPDA) Curing Agent
Isophorone Diamine (IPDA) is a cycloaliphatic primary diamine used as a curing agent for epoxy resins, delivering non-yellowing, high-gloss coatings and adhesives with excellent UV stability. Its cycloaliphatic structure imparts higher Tg and better outdoor durability than linear aliphatic amines, while its moderate reactivity allows adequate working time. IPDA-cured epoxies are widely used in decorative floor coatings, clear adhesives, and UV-stable aerospace coatings.
