Tested Product Type: Coatings/Lubricants
ASTM D7234-22
Pull-Off Strength of Coatings on Concrete Using Portable Pull-Off Adhesion Testers
This test evaluates concrete coatings systems to determine the greatest perpendicular force that a surface area can bear before a plug of material is detached. Failure will occur along the weakest plane within the system comprised of the loading fixture, glue, coating system, and substrate. Both force and fracture mechanism are typically reported. This test is limited to adhesion strengths of up to 500 psig.
