Comparative Analysis of Coating Adhesion Testing Standards
Adhesion is a key indicator for evaluating coating performance,and its quality directly affects the anti-corrosion performance and service life of the coating.The commonly used coating adhesion testing methods at home and abroad are mainly divided into five categories:Cross-cut test,X-cut test,Circle-drawing test,Pull-off test,and Warp-peel test.This paper introduces the five types of adhesion testing methods and standards,and analyzes the differences from the aspects of application scope,instrument equipment,samples,environmental conditions,and result evaluation.It provides reference for coating enterprises and testing institutions to choose suitable adhesion testing standards,which can further improve the technical level of the coating industry.
