Because of the importance of paints and coatings as the primary-means for corrosion protection, increasingly sophisticated analytical instruments are being developed and brought to bare monitoring all stages of the coating process. This includes both QA/QC during coatings manufacture and application as well as during the investigation of coating failures years after. Microscopic-FTIR, auger, XPS/ESCA spectroscopy, thermal analysis (including DSC, TGA, and TGA/FTIR), SEM coupled with EDX, as well as gas and gel permeation chromatography are but a few techniques available to the investigator wishing to solve (or prevent) coating problems. These are discussed along with some specific applications and instrumental limitations.
