This paper on the use of Fourier transform infrared spectroscopy and instrumental determination using algorithm-based comparison of spectra is comprised of an orientation to the basics of instrument use and sample preparation, followed by a review of test programs and results of instrument-based spectra comparisons of numerous industrial coating types. The chemical molecular bonds associated with each coating type used to generically identify the coating types will be reviewed as background information.
The use of duplex coating systems (hot dip galvanizing or thermal spray coating with one or more liquid-applied coatings) for long term protection of structural steel is becoming more mainstream in many industries. This paper describes the advantages of employing duplex coating systems as well as some important considerations for designers prior to specifying their use. It also highlights an ongoing initiative to help agencies more efficiently and effectively use duplex coatings on steel bridges by developing guidelines, standards, and other materials.

The role of a Coating Inspector has evolved considerably over the past few decades, and the responsibilities have increased over what used to be a rather straightforward job: to verify that surface preparation and coating application meet the project specification requirements. Today there are week-long or multi-week basic and advanced coating inspection courses, specialty courses that are industry-specific (e.g., bridge, nuclear), courses that are substrate-specific (e.g., concrete coatings inspection) and even coating-specific (e.g., inspection of thermal spray coatings).
The Paint and Coatings industry uses accelerated testing to extrapolate performance in real world situations and ensure coating formulations will withstand the forces of nature and provide long-term durability. This paper will compare the performance data of the three most common accelerated exposure test methods: QUV-A (ASTM D 4587), Xenon Arc (ASTM D 6695), and EMMAQUA (ASTM D 4141) and correlate this data to the same systems exposed for 10 years in South Florida and in North Kansas City, Missouri.
