Digital Pull-off Adhesion Tester for Paint Film

The instrument uses a hydraulic system to vertically pull a probe of a specific size away from the coating surface. A sensor records the maximum pulling force at the moment of separation, and the adhesion strength is calculated based on the probe's area. It is used to evaluate the bonding strength between the coating and the substrate, verifying the adhesion quality of coatings in fields such as steel structure corrosion protection and automotive painting.
Selection
Select the appropriate range model based on the thickness of the coating being measured. Determine the probe size by considering the flatness of the substrate. Verify that the instrument’s accuracy complies with ASTM D4541/ISO 4624 standards. Prioritize equipment with data storage functionality. Ensure the adhesive used is compatible with the coating characteristics. Regularly calibrate the pressure sensor using a standard block.
