Calibrating the climate: II: Correlations between different weathering tests
article
In 2001, TNO completed a major project on the performance of more than 30 different coil coating systems [1, 2]. The main objective was to investigate corrosion protection through artificial corrosion tests and outdoor exposures, which were continued for up to ten years. Gloss measurements were performed to obtain information on the weathering behaviour of the top coatings. The first part, published, in ECJ 1-2/20 06 [3] examined test results and the effects of test conditions on gloss retention. Here, the correlations between the various tests are examined. It is concluded that only one accelerated test correlates reasonably well with some outdoor exposures, and then only for the non-polyester systems. Improved artificial weathering tests must therefore be developed to allow more reliable prediction of outdoor weathering performance.
