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.
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.
Elcometer offer a highly comprehensive range of Adhesion Gauges designed specifically to meet your requirements.
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 |

An extremely versatile hydraulic adhesion tester which will cope with many adhesion test requirements. Test can be made on flat or curved (concave and convex) surfaces. A reusable dolly is adhered to the coating's surface and the force required to push the dolly from the surface is applied using the handle. The value of the force applied is displayed either on a digital display or on an analogue dial. Conforms to ISO, ASTM, BS & EN.
