Summary
INFRARED (IR) SPECTROSCOPY IS AMONG THE OLDEST and most valuable of the instrumental techniques available to the coatings laboratory. It permits investigation of materials in nearly any physical form; liquid, solvent solution, cast film, ground powder, and even dried paint are amenable to this technique. While transmission of the IR beam through a thin film is the preferred mode of analysis, a wide range of accessories permit examination of nearly any kind of sample. IR provides qualitative data not easily generated by other analytical techniques. This is especially useful for probing industrial problems, where one spectrum can frequently produce all information necessary for the solution. Coupling IR instruments to computers has vastly increased their effectiveness. Spectral subtraction can often reveal hidden components and produce separations that are not practical chemically. The identification of unknown materials is now readily performed by spectral searching using digital pattern matching. The evaluation of curing, weathering, and durability chemistry can be conducted on new formulations. IR spectroscopy is currently being used to do quality assurance. Over the past four decades IR instrumentation has grown until it is now an essential part of any coatings laboratory.
