A solvent action parametrisation scheme has been developed combining relevant parameters of the solvent action on modern artist’s paints to characterise the solvation and dissolving properties of different binding media. The new system combines different concepts used in solvent chemistry. It is based on the normalised and solute dependent dimension [hδH + eET(30)cv]N. It comprises a polarity value ET(30)cv as the magnitude of the enthalpy, and a combined value representing the cavitation energy δH as an entropy-influencing factor. 48 solvents were divided into 5 subgroups based on their interaction and structural properties. This binary scheme permits to reliably quantify spaces of efficiency. The graphical selectivity of the scheme was applied to 4 binding media systems (oil, alkyd, acrylic-, and acrylic-polystyrene) by determination of the swelling capacity of 48 solvents. The graphical visualisation of the systematic parametrisation of solvents permits to judge the intermolecular interaction and other effects of solvation relevant to the restoration of painted artwork.
