This standard specifies the adhesion disbonding test method for Paints and varnish, which is used to evaluate the adhesion of coatings on different substrates. The test measures the peel strength of coatings after being stressed by applying a disbonding force to the coating surface to judge the adhesion performance of coatings. The standard describes in detail the test equipment, sample preparation, operation procedures and evaluation criteria to ensure the accuracy and conformity of the test results. This method is widely used in the field of coating production, quality control and research, especially in the automotive, construction, home appliances and other industries. Through this test, it is possible to effectively evaluate whether the coating will peeling or disbonding during use, help improve the mass and durability of the coating, and ensure the long-term Stability of the coating in practical applications.
