Powder Film Bending Tester

The powder film bending tester detects coating cracking or peeling by bending a test piece coated with powder around a specified axis. It is used to evaluate the adhesion and flexibility of powder coatings during deformation and is suitable for quality control in the coating of metal products.
Selection
When selecting, consider the diameter range of the bending axis as required by the testing standards to ensure the fixture is compatible with common substrate thicknesses. Pay attention to the smooth operation of the bending mechanism and check whether the sample fixation method is anti-slip. Confirm that the instrument structure can avoid secondary scratches on the coating, and ensure the reading device clearly displays the bending angle.
