A Pull-Off Adhesion Tester measures the tensile bond strength (pull-off strength) of coatings, paints, concrete repair mortars, waterproofing membranes, and surface treatments by measuring the force required to pull a test dolly away from the substrate. Compliant with ASTM D4541, ISO 4624, and IS 13620, it is used to verify that applied coatings and repair systems have adequate adhesion to their substrate. Widely used by corrosion protection contractors, infrastructure maintenance teams, waterproofing applicators, and NABL-accredited material testing laboratories. JS Civil Lab Solutions supplies pull-off adhesion testers with calibration certificate and AMC support across India. Call +91 93596 24761 for pricing.
A pull-off adhesion tester is a field and laboratory instrument that measures the tensile bond strength of a coating, paint, repair mortar, adhesive, or surface treatment by measuring the maximum force required to pull a metal test dolly away from the applied surface perpendicularly. The result — expressed in MPa or N/mm² — is the adhesion strength (pull-off strength) of the coating system to its substrate.
Pull-off adhesion testing is specified in ASTM D4541, ISO 4624, and IS 13620, and is the industry standard method for verifying that protective coatings, concrete repair mortars, and waterproofing systems have adequate adhesion before and after application.
