Epoxy resin is a class of thermosetting polymeric compounds containing reactive epoxy groups. It provides high adhesion, mechanical strength, chemical resistance, electrical insulation, heat resistance and dimensional stability. After curing with hardeners, it forms rigid cross‑linked structures and is widely used in coating, bonding, electronics and composite industries.
