    The effect of the transport properties of epoxy based coatings on metallic substrate corrosion

    An attempt is made to correlate the protective properties of different epoxy based coatings with their water transport propertieS. Rust formation on the support and blister growth on the varnish are strongly affected by the equilibrium uptake and diffusion coefficient of water. An evaluation of these parameters can give useful information on the capability of different paints

    Hygrothermal ageing of epoxy based coatings

    Water sorption kinetics, and equilibria at different temperatures, and mechanical tests have been performed on different epoxy based coatings. The resins show different water transport properties and consequently different mechanical properties of the wet system, depending on the temperature and formulation. This can be explained in terms of water plasticization and microcavity formation in the system when exposed to high temperatures
