The feasibility of physical property assessment of waterborne automotive paint emulsion system using Fourier transform Raman spectroscopy (FT-Raman spectroscopy) was examined for viscosity as an example trait. The experiment was performed under the same temperature both in conventional and Raman spectroscopic methods aiming the online control. Raman spectroscopic data and the partial least squares (PLS) regression revealed highly significant correlation between conventionally measured and Raman predicted viscosity with correlation coefficient (R2) >0.935 in the calibration and in the prediction. The calibration model was considered to explain viscosity by the interactions between chemical components and water from the assignment of important frequencies. Raman spectroscopy coupled with multivariate data analysis will give to monitor rich chemical and physical information simultaneously and significantly in the process to contribute the final property of automotive coatings such as strength and weather durability.
