Cup Convex Tester for Paint Films

The paint film cupping tester uses a hemispherical punch to uniformly press against the back of the sample, measuring the maximum indentation depth when the paint film cracks or peels. It is used to evaluate the resistance to cracking, ductility, and adhesion of coatings during deformation, and is suitable for quality testing of coatings on substrates such as metals and plastics.
Selection
When selecting, consider the indenter speed and range required by the test standards to match the common sample thickness range. Pay attention to the wear resistance of the indenter material and the accuracy of displacement measurement to ensure the structural stability of the equipment. Choose suitable fixtures based on the sample size, and confirm that the data output method meets recording requirements.
