The characterization of coatings utilizing thermal extraction/gas chromatography followed by fourier transform infrared spectroscopy and/or mass spectrometry is a very powerful hyphenated technique capable of providing definitive answers to questions of QA/QC during the development of a paint formulation, during its manufacture, during its application, or during its investigation after a coating failure. Small recovered paint chips reveal a portion of their past history. Positive identification of generic binder types, solvent entrapment, unreacted monomer, and improper catalyzation are demonstrated. Plastic type and degree of degradation may be identified. An introduction to the versatility of the instrument is presented.
