Coating adhesion testing
WebAdhesion testing after the coating process will quantify the strength of the bond between substrate and coating, or between different coating layers or the cohesive strength of some substrates. Routine adhesion tests are used as part of inspection and maintenance procedures to help detect potential coating failures. WebPull-off adhesion testing is a method of measuring the resistance of a coating to separation from a substrate when a perpendicular tensile force is applied. There are range of substrate materials that the testing is usually performed on, including metals, plastics, concrete, wood and glass.

WebA quantitative adhesion test consists of epoxying a stud to the coating and recording the force required to pull the coating from the substrate. This test is not covered in the Mil-standards. Abrasion and adhesion might be tested (no sooner than a specified time) after humidity exposure. WebAdhesion tests provide insight into the bond between a substrate and the applied coating or paint. Coating adhesions tests produce intentional coating failures that allow experts to examine the potential causes and consequences of the failure. Unforeseen coating failures can lead to costly repairs, damaged equipment, and catastrophic failure.
