Pull-off Method Coating Adhesion Tester

The pull-off coating adhesion tester uses hydraulic or mechanical means to vertically pull fixtures bonded to the coating surface, measuring the tensile force required to separate the coating from the substrate. This value reflects the bonding strength of the coating and is used to evaluate the adhesion performance of coatings and inks on materials such as metals and plastics, guiding adjustments in production processes.
Selection
When selecting, consider the thickness of the coating to be tested and the type of substrate to match the instrument's measurement range and accuracy. Verify testing standards such as ISO 4624 or ASTM D4541. Ensure the instrument is equipped with suitable fixtures and adhesives. Evaluate operational convenience and data recording functions. Confirm maintenance requirements and environmental adaptability of the equipment.
