Abstract: A low temperature curing accelerator is synthesized by Michael addition reaction of polyethylene polyamine and acrylate. Thus, a low temperature curing solvent-free epoxy anticorrosive coatings for ballast tank has been developed, wherein the glycidol ether epoxy resin/bisphenol A epoxy resin is employed as matrix resin and the modified cycloaliphatic amine is employed as curing agent cooperated with appropriate amount of the synthesized curing accelerator, furthermore, fillers and pigments are selected for coating modification.The coating performance and influence of different curing agent on low temperatu curing effect are investigated. The results show that the coatings give fast low temperature curing rate, excellent toughness, and great resistance to cathode stripping and salt spray corrosion.
