paint film cupping tester technical indicators

　　The paint film cupping tester is suitable for evaluating the resistance of coatings(single layer or matching system coatings)of paints,clear paints,and related products to cracking or separation from metal substrates after gradual deformation,and evaluating whether the coating passes or does not.It is also possible to gradually increase the depth of indentation to determine the minimum depth at which the coating begins to crack or detach from the substrate.
