ABSTRACT
The influence of chloride and sulfate ions on the steel surface on the durability of selected paint systems — water- and solvent-borne as well as mixed systems was investigated. The accelerated tests were conducted in salt spray and Prohesion chambers as well as in water and NaCl solution. The systems were also exposed to the natural environment, in rural and urban-industrial atmospheres. The corrosion damage was evaluated visually and by means of impedance spectroscopy. The variable influence of chloride and sulfate on the tested systems was determined. A possible correlation between accelerated tests and the actual damage to systems at corrosion sites is discussed.
