Epoxy Curing Agent
Epoxy curing agents are hardeners specifically formulated to react with epoxide groups via ring-opening addition, producing highly crosslinked thermoset polymers with outstanding adhesion, chemical resistance, and mechanical performance. Common chemistries include polyamines, polyamides, anhydrides, and phenalkamines, each imparting distinct performance profiles to the cured epoxy system. Epoxy curing agents are the backbone of protective coatings, structural adhesives, civil engineering, and composite applications worldwide.
