Abstract:
In the marine environment, the corrosion of steel structures is inevitable. The organic coating is the most effective, economical and widespread way to slow down the metal corrosion. High solid epoxy coating has been widely used in heavy duty anticorrosion area due to its green feature, good compactness and high thickness. In this review, the progress of the high solid epoxy coating, the existing problems and the appropriate solutions are described in detail. The epoxy resin and amine curing agent for film formation play a key role in the properties of the coating. A series of practical methods of toughening epoxy resin for high solid epoxy coating has been summarized. Besides, impact and thermo resistant, and low temperature and underwater curing agent should be developed. The mannich base type epoxy resin curing agents can meet various performance requirements. This paper describes the research progress in the synthesis of the mannich base type curing agents
