NF T37-001-6-2020 《Coil coated metals - Test methods - Part 6 : adhesion after indentation (cupping test)》 Related products

The NF T37-001-6-2020 specifies the test method for coil coating metals. Part 6 focuses on the determination of adhesion after indentation and is tested by Cupping test. This standard evaluates the adhesion strength between coatings and substrates by simulating the deformation of coatings after indentation. Cupping test can effectively detect the durability of coatings under the mechanical stress that may be encountered in actual use, and is especially suitable for applications with high coating adhesion requirements in the automotive, home appliance and other industries. This test method provides manufacturers with a basis for evaluating coating mass and optimizing coating processes, which helps to improve the compression resistance and long-term Reliability of products.
