In order to better understand the performance of general anticorrosive primers,five different types of general anticorrosive primers were selected for performance comparison test.By carrying out routine physical and chemical tests and coating environmental tests,and then sorting and analyzing the test data,the performance of anticorrosive primer products was systematically evaluated.Finally,two kinds of general anticorrosive primers with excellent anticorrosion performance were selected,and the selection of general anticorrosive primers in practical construction and application was provided with certain basis.
