Single-sided NMR has been demonstrated as a useful technique for the inexpensive and non-invasive study of cultural heritage objects, including numerous different painting and paint samples. The relatively recent invention of water-miscible oil paints – a new form of environmentally friendly oil paint that can be thinned and cleaned by water – provides a need for analysis of the physical properties of the cured paint films. Single-sided NMR offers an excellent analytical tool to study the structural effects of the emulsifying agent present in water-miscible oil paints on the paint linoxyn network by measuring the transverse (T2) relaxation times for various pigments. In this research, single-sided NMR is shown to be a successful technique in analyzing the physical properties of oil paint networks in comparison to the chemical composition of the paints as assessed by fatty acid ratios produced from complimentary GCMS data. The discovery of a correlation between specific fatty acid ratios and relaxation times suggests that the presence of the emulsifying agent interferes with autoxidation and the cross-linking of the paint network, impeding the relative rate of curing. The conclusions drawn from this research offer the potential for multiple new experiments to better understand the chemistry behind the curing of oil paints in the presence of an emulsifying agent.
