From cutting and one-step correction to final finishing.
FTIR Analysis of Coatings: Chemical Information Is Not a Durability Test
FTIR can provide information related to chemical bonds and molecular signatures. It does not by itself measure the coating's service life.
Updated · NANOLAB Knowledge
Practical approach
Ask the laboratory what question the spectrum can answer and which references or preparation methods are needed.
A spectral similarity can support an identity investigation while leaving adhesion or weathering performance untested.
Decision limits
Do not turn a chemical-analysis image into a blanket performance certificate.

Method reference: Thermo Fisher: FTIR sample handling. References describe their stated methods or products; they do not certify NANOLAB products or establish compatibility with an unlisted surface.
Ask NANOLAB about the exact product and intended use. Use the current product documentation for formulation-specific instructions.

Right-Censored Durability Data: A Test Ending Is Not a Coating Failure
Record right-censored durability observations correctly when a coating still meets the criterion at the end of a study.
Ceramic Coating Test Reports: Handling an Outlier
Investigate an unusual coating test result with a documented process instead of automatically deleting it or treating it as definitive.
XPS Analysis of Ceramic Coatings: Surface Composition Is Not Bulk Composition
XPS is strongly surface-sensitive. Its reported composition describes the analysed near-surface region rather than automatically representing the entire bottle or film.
