Shop onlineAdhesion Testers
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 additional costs of 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 adhesion tests are used as part of inspection and maintenance procedures to help detect potential coating failures. When selecting an adhesion gauge, it is important to use the same inspection test methods throughout the inspection to ensure accurate comparisons.
Frequently asked questions
How can I select the correct adhesion gauge?
Match the gauge to your substrate, coating and the standard you test against, for example ISO 4624 or ASTM D3359, then use the same test method throughout the inspection so results stay comparable. The pull-off, push-off and cross-hatch testers listed above each suit different applications.
What is the main use of adhesion testing?
Adhesion testing is used to quantify the strength of the bond between substrate and coating, which helps in detecting potential coating failures.
Why is it important to use the same test methods?
Using the same inspection test methods throughout the inspection ensures accurate comparisons.
