Paint components

(Click on the name)





In this page a selection of ATR-FT-IR spectra of various pure paint components ( pigments, binders, fillers) in the mid-IR and far-IR region are presented. All measurements were carried out using a Thermo Scientific Nicolet 6700 FT-IR spectrometer with a “Smart Orbit” micro-ATR accessory.

These infrared spectra have been recorded at University of Tartu (Estonia), Institute of Chemistry, Chair of Analytical Chemistry. The spectra have been acquired over the last couple of years in the course of various projects on historic, industrial and construction paints, coatings and pigments.

In the course of the research of inorganic pigments and the usefulness of ATR-FT-IR for identification of inorganic pigments using the low wavenumber region (550–230 cm–1) two papers have been published (Spectrochimica Acta Part A, 2009, 73, 764–771 and Spectrochimica Acta Part A, 2010, 75, 1061–1072) and a doctoral thesis has been defended. In our recent paper (Spectrochimica Acta Part A, 2014, 133, 207–213) the applicability of ATR-FTIR with PLS data analysis for quantifying the components of paint binders and pigments was demonstrated.
