The waterborne epoxy anti-corrosive primer is quite different from the oil-based epoxy anti-corrosive primer which uses volatile organic solvents because water is used as the main solvent and diluent in the former.The permeability of water in the waterborne epoxy anti-corrosive coating has a impact on the performance of the coating film,especially on the wet adhesion and anti-corrosion properties.Therefore,this study provides a very important improvement approach how to enhance the performance of waterborne epoxy anti-corrosive coatings.This paper studies the effects of water absorption rate and water absorption amount of waterborne epoxy-corrosive primer coating film on the wet adhesion,anti-corrosion and gloss of the waterborne epoxy anti-corrosive coating.
