By using medium molecular weight epoxy resin,adding environmentally-friendly anti-rust paint zinc phosphate,anti-sinking and non-dispersed polyamide wax variable agent,and the waist-fruit shell oil modified phenolic amine curing agent,the primer-topcoat in one steel structures anticorrosive coatings with quick-drying was prepared,which was an environmentally friendly product with high solid content and low VOC content.The coating has the advantages of fast drying,fast low temperature curing,high surface luster,good color retention,good smoothness and low viscosity and easy construction,and good adhesion with the substrate,excellent permeability resistance and anti-corrosion performance.
