The rate of water transportation and the degree of saturation of polymeric coatings depends on exposure history, exposure environment, and the nature of a coating. The focus here is on the time taken for transport of water and the variation it causes in thermal and mechanical properties, which have also been shown previously to have time-dependence that leads to discrepancies between different weathering regimes. This paper studied the effect of moisture on coatings’ mechanical properties and the effect of moisture and temperature on recovery of surface indentation. The reduction of mechanical properties and the increasing rate of surface defect relaxation can be explained in terms of plasticization by water. Recovery of surface defects is related to the appearance and diffusion activity of coatings during exposure. Thermogravimetric analysis showed that the content of moisture in the sample is determined by the ambient humidity, temperature, and the rate of change in these environmental parameters. Diffusion coefficients were determined from the weight change data and an activation energy was obtained via Arrhenius equation. Changes in yellowness, as an example, and signature of chemical degradation, indicated that the cycling period in accelerated weathering may affect the degradation via the amount and distribution of moisture in coatings. Diffusion of moisture is typically slow and limits the possibility of complete drying or saturation in an exposure cycle. Results from the cumulative effect of many cycles will be different depending on the conditions DOI : 10.1007/s11998-009-9209-x En ligne : https://link.springer.com/content/pdf/10.1007%2Fs11998-009-9209-x.pdf Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=9764

A major challenge has been that light stabilisers may migrate from the coatings into the plastic substrate, accelerating coating degradation. Non-migrating HALS can greatly improve performance, while some migrateable types degrade certain substrates.

Titre : Combined corrosion/weathering : validating a concept with over a decade of research Type de document : texte imprimé Auteurs : P. Brennan, Auteur ; D. Zeise, Auteur ; J. Regan, Auteur Année de publication : 2009 Article en page(s) : p. 109-114 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Revêtements 'Emulsion acrylique' Silicone Détérioration 'Effets ultraviolet' 'Corrosion/détérioration ' 'Test corrosion accéléré' Index. décimale : 667.9 Revêtements et enduits Résumé : Corrosion/weathering tests - When coatings degrade from UV exposure, they can become more susceptible to corrosion attack. In the early 1990s, ISO and ASTM standardised a combined corrosion/weathering cycle. Today, this is still considered the most effective test method for determining the usefulness of industrial maintenance coatings.
This paper reviews current corrosion/weathering tests results on different industrial maintenance coating systems, including lower VOC coatings such as waterborne acrylic coatings and silicone-based coatings. Additionally, some of the industry's leading experts provide their insights into corrosion/weathering testing as well as recommendations for modified cycles developed for special applications.Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=9049
