This paper focuses on the influence of ultra-fine glass fiber on the coating properties. Diglycidyl ether of bisphenol-A and diglycidyl ether of bisphenol-F epoxy resins were used as film former. Salt spray test and electrochemical impedance spectroscopy （EIS） were employed to characterize the anticorrosion properties of the coatings. Experimental results indicate that the diglycidyl ether of bisphenol-A epoxy resin can improve the coating hardness, while the diglycidyl ether of bisphenol-F epoxy resin has better anticorrosion properties.
