TY - CONF A1 - Raedel, Martina A1 - Bücker, Michael T1 - Long term corrosion protection - A contradiction in terms? A comparative study of modern and traditional anticorrosion systems N2 - A comparative study tested the performance of modern anti-corrosion Systems against that of traditional red lead Systems. One aim of the research project was to find alternatives for the use of a red lead priming coat, the Standard anti-corrosive primer for iron and Steel in the past but a material which endangers health as well as environment. The investigation aimed to determine whether anti-corrosion Systems developed for industrial use were suitable for the Conservation of historic iron and cast iron objects. Besides coatings containing red lead, several surface tolerant coatings with different anti-corrosion pigments were examined. The modern anti-corrosion Systems examined were suitable for surfaces where Optimum surface preparation is not practical. They were applied to both historical samples and to newly prepared model samples. After uniform pre-corrosion, the model samples were coated and underwent two different ageing procedures: accelerated ageing in a climate chamber and outdoor weathering on a test site with moderate city climate. The specimens were exposed for more than two and a half years. Evaluation of the artificially aged samples was carried out under the aspect coating degradation, tensile strength test, cross-hatch test and Fourier-transform infrared microscope. The results of the research with optical evaluation and test procedures will be presented. The two ageing methods will be discussed, with different results from the naturally and artificially aged samples. The results Show a similar eligibility of modern anti-corrosion Systems as compared with red lead Systems for the use in Conservation.
