GB/T 9286-1998 "Cross-cut test for Paints and varnish films" was revised according to the international standard ISO 2409:1992. This standard applies to the evaluation of the adhesion performance of coatings between right-angled grid graphics and substrates after cutting. Compared with ISO 2409:1992, this standard has been adjusted in terms of reference standards and test methods, especially in terms of Coating thickness determination, condition adjustment and adhesive tape application. The standard specifies in detail the spacing of cutting, the choice of cutting tools, and manual operation procedures. In addition, the standard also describes the selection and treatment of test plates, including painting, drying and Coating thickness determination. This standard applies to coatings on hard and soft substrates and provides an important mass assessment tool for coatings and their applications.
