Modification of Epoxy Resins Used for Heavy-Duty Coatings

epoxy resin is one of the three-big film-former substances,which used in heavy-duty coatings,and whose structure chains determine their anticorrosive properties,therefore modification of epoxy resin is an important method of improving anticorrosive properties of epoxy paints systems.The modification methods and mechanisms of epoxy resins with high performances are reviewed,and a description is also given on their application heavy-duty coatings.
