The objective of this work is to develope methodologies with different techniques to quantify permeability, diffusivity and solubility of water in model system coatings. These properties are of primary relevance in corrosion protection coating studies. Permeabilities are measured successfully by Microclorimetry, Gravimetry and Thermogravimetric Analysis (TGA). Solubilities are measured by means of Gravimetry and Fourier Transfomred Infra-red Spectroscopy (FT-IR) analysis. Both methods to perform sorption measurements are successful in following water uptake kinetic curves, being complimentary in suitable thickness range for the measurement. The validity of permeabilities calculated from permeation measurements, are verified by group contribution methods and reported values in literature. Diffusivities were measured by using data from the transient region in sorption and permeation measurements, as well as being calculated by considering the steady state permeation rate and equilibrium solubility in permeation and sorption measurements, respectively. These diffusivities are verified by values reported in literature.
