The Agilent 4100 ExoScan FTIR can be used to effectively measure epoxy primer thickness on aluminum. The calibration technique facilitates accurate predictions. Sensitive enough to detect even small discrepancies in thickness, the system is ideal for use in aircraft applications.
The document details a study demonstrating that the handheld Agilent 4100 ExoScan FTIR can effectively measure the thickness of epoxy primers on aluminum surfaces. The technique utilizes the absorbance of specific IR spectral bands, which is directly proportional to the coating thickness, allowing for non-destructive analysis even on thin layers.
It is used to measure the thickness of epoxy primer on aluminum.
A sample measurement takes about 8 seconds.
The absorbance falls within the linear range of 0.05 to 1 absorbance units.
