Coating Test Panels: Use a Blank to Investigate Handling Contamination
A handling blank can help investigate contamination introduced by preparation, packaging or transport. It serves a different purpose from a performance control.
Updated · NANOLAB Knowledge
Practical approach
Ask the laboratory to define an appropriate blank and carry it through the relevant handling steps.
Material detected on both the specimen and its handling blank may require investigation before being attributed to the coating.
Decision limits
Do not subtract or dismiss a blank result automatically. Use the laboratory's validated interpretation.

Investigate an unusual coating test result with a documented process instead of automatically deleting it or treating it as definitive.
Reading an Adhesion Test Report for a Nano Coating
Read nano coating adhesion reports by checking the substrate, preparation, test method and failure observation instead of relying on a pass label alone.
Coating Test Panels: Keep the Backing Consistent
The support behind a sample can affect how a test is performed or observed. Unrecorded backing changes introduce another variable into comparisons.
