The TCVN 2097-2015 standard specifies a cross-cut test method for the adhesion of Paints and varnish coatings. This method evaluates the adhesion strength between coatings and substrates by cross-scratching on the surface of the coating, followed by sticking and tearing operations using tape. The test results are graded according to the degree of coating disbonding to judge the durability and mass of the coating. This standard is widely used in Coatings production, quality control and research to ensure the Reliability and performance of coatings in practical applications.
