Description
From the largest man-made structures to the smallest household appliances, most manufactured products have a protective or cosmetic coating. Premature failure of this coating can, at the very least, result in costly penalties or rework. A Push Off Adhesion Tester can be used to test for these failures.
Adhesion 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 testing is used as part of inspection and maintenance procedures to help detect potential coating failures.
Push Off Adhesion Method Similar to the Pull Off Adhesion Test, a dolly is glued to the coating. When the adhesive has cured, however, the dolly is pushed off the surface by the adhesion gauge.
Advantages:
Fast cure time adhesives can be used, ideal for curved surfaces
Possible Limitations:
High forces exerted by gauge may cause thin substrates to deform
Applications:
Pipelines and metal spray coatings
