Sorption of SO2 in latex paint films is measured as a function of time. This data is used to extract the solubility (S) and the diffusion coefficient (D) for SO2 in these films. The solubility of SO2 in each of the samples follows Henry's law behavior. Sorption occurs only in the polymer, with the inorganic pigment particles acting as impenetrable fillers. The diffusion of SO2 is Fickin with an exponential dependence upon the concentration of SO2. This data is used to calculate the permeabilities of the paint samples to SO2, at levels typically found in the atmosphere.
