Adhesion test for tinplate

Adhesion testing on tinplate involves creating scratches on the surface of tin-plated steel using the cross-cut or circular scribing method. The degree of coating peeling reflects the bonding strength. This method is used to evaluate the adhesion performance of coatings and inks on metal packaging materials, ensuring that printed patterns and protective layers do not detach during processing and transportation.
Selection
When selecting, consider matching the substrate thickness with the sample to be tested, as the surface tin plating amount affects the test results. Choose the cross-cut tool specifications based on the coating thickness, and ensure the comparison card for observing the peeling area complies with industry standards. Control the temperature and humidity of the test environment to be consistent with actual application conditions.
