Abstract: Alkyd resin is a resin that has been largely produced and intensively applied in domestic market. Three typical methods of alkyd resin modified with epoxy were reviewed: physical blending modification. solvent epoxy modified alkyd resin and waterborne epoxy modified alkyd resin. Meanwhile. factors affecting the preparation of waterborne alkyd resin modified with epoxy and the film performance were discussed, such as types of epoxy resin, types, amount and oil length of mono fatty acid. Finally the application prospect of epoxy modified waterborne alkyd resin was described.
