Pull-off Adhesion Tester for Paint

The pull-off adhesion tester uses a hydraulic system to vertically pull an aluminum dolly bonded to the coating surface, measuring the force required to detach the coating from the substrate. It is used to evaluate the bonding strength between the coating and the substrate, commonly applied in quality testing for automotive and marine coatings.
Selection
When selecting, consider the maximum tensile range matching the coating type to ensure the instrument's accuracy complies with ASTM D4541 standards. Check that the fixtures are compatible with different substrate shapes and confirm the stability of the hydraulic system. Prioritize models with digital display and data output functions for easy recording.
