Pull-Off Adhesion Testing Instrument

The pull-off adhesion tester measures the maximum force required to detach a coating from its substrate by adhering a test dolly of specific diameter to the coating surface and applying a uniform tensile force perpendicularly. This instrument is used to evaluate the bonding strength between the coating and the substrate, commonly applied in quality control within the paint and ink industries to assess the durability of coatings in practical use.
Selection
When selecting a pull-off adhesion testers, consider matching the maximum tensile range to the sample strength, ensuring the test dolly size is suitable for the coating thickness, and verifying that the loading rate is adjustable to comply with standards. Pay attention to the instrument's accuracy and calibration certificates, prioritize durable construction, and check for complete accessories, such as adhesives, to facilitate use in both field and laboratory settings.
