Paints and adhesives, although dissimilar materials with different purposes, have a commonality that they are typically liquid phase starting materials that end up as solid materials after a drying or curing period. Attenuated Total Reflectance (ATR) FTIR sampling methods are used extensively within the coatings and adhesives industries for the characterization of raw materials and product formulations.
This application note describes how ATR measurements carried out on a PerkinElmer Spectrum Two FTIR can be extended to monitor the changes taking place over time as the material dries or cures.
