The ISO 2409 standard specifies a method for cross-cutting tests of Paints and varnish coatings to evaluate adhesion between coatings and substrates. This test involves a series of uniform scratches across the coating surface to form a grid shape. The adhesion of the coating is then observed through a tape pull test to assess whether the coating will peeling or disbonding. ISO 2409 is widely used for quality control of various coatings, especially in areas where coating adhesion is critical. This method is simple and easy to operate, providing important data on coating performance, helping manufacturers and users to ensure the mass and durability of coatings.
