Waterborne coatings was an important direction for environmentally friendly development. A systematic evaluation and analysis of waterborne coatings were conducted based on the advantages and disadvantages of products，performance characteristics，field application results and comprehensive costs of waterborne coatings. The results indicated that waterborne coating with a service life of over 3 years have been pulverization，and the degree of pulverization of the coating increased with the extension of service life. The average price of waterborne coatings was 41. 7% higher than that of solvent based coatings of the same type，and the cost of anticorrosive engineering projects using waterborne coatings was 13. 0% higher than that using solvent based coatings. Quality control measures about key links such as raw materials，construction environment，painting process，and completion inspection were proposed. The application scope of waterborne coatings in the petrochemical field was clarified. All the above provides practical data and technical support for the application ofwaterborne coatings in the petrochemical industry.
