TaninsIndex. décimale : 667.9 Revêtements et enduits Résumé : The natural exposure and water absorption tests carried out within European Standard EN927 use clear, knot-free wood in order to minimise variability in the results. However, knots are common in practice in many coated timber components, and it is widely acknowledged that the performance of paints can be compromised over knots or timbers that possess a high tannin content. As part of the European Standard for evaluating the performance of coatings on wood, a validated method is required for evaluating the discoloration due to tannin staining and resin exudation from knots. CEN/TC139 Working Group 2 has been charged with identifying a reliable method of testing for tannin stain resistance and producing a standard; identified as EN927-7 'Resistance to tannin staining'. This paper presents results from two laboratories on an evaluation of a Trätek standard procedure. Results of discoloration are presented for panels containing knots that have been coated with one of two test coatings. Reflectance spectrometry and digital imaging-based methods of evaluating discoloration were used and an interpretation of the comparability of the techniques is provided. The suitability of the method for promoting to WG2 as a standard is presented on the basis of these results. Note de contenu : - EXPERIMENTAL : QUV with spray - QUV without spray - Window exposure

Test d'immersionIndex. décimale : 667.9 Revêtements et enduits Résumé : The aim of this study was to produce graphene oxide (GO) coatings on biodegradable AZ31B magnesium (Mg) alloy. GO was synthesized by improved Hummers’ method, and a suspension was prepared in deionized water by ultrasonication. GO coatings were developed on AZ31B Mg alloy by electrophoretic deposition (EPD). The EPD parameters, such as voltage and time, were optimized to obtain uniform GO coatings. Characterization was carried out using Fourier transform infrared spectroscopy, X-ray diffraction, atomic force microscopy (AFM), and scanning electron microscopy. GO was found to have a thickness of approximately 0.7–1 nm as determined by AFM. Electrochemical behavior of coatings was evaluated by Tafel analysis and electrochemical impedance spectroscopy (EIS) in Ringer’s lactate solution. GO coatings improved the corrosion resistance of the AZ31B Mg alloy by 16× in Ringer’s lactate solution as compared to bare Mg alloy.

Revêtements -- DétériorationIndex. décimale : 667.9 Revêtements et enduits Résumé : Exterior durability of coatings refers to their resistance to change during outdoor exposure; such changes include changes of modulus, loss of strength, embrittlement, discoloration, loss of adhesion, chalking, loss of gloss, and environmental etching. Thus, both aesthetic and functional properties are involved. The terms outdoor durability and weatherability are also used. The most common chemical processes leading to degradation of coatings are photoinitiated oxidation and hydrolysis resulting from exposure to sunlight, air, and water. These processes are interrelated, including enhanced photoxidative degradation in high humidity and enhanced hydrolytic degradation during photoexposure. Furthermore, both processes are accelerated by higher temperatures. Hydrolytic degradation may be enhanced by exposure to acid, as from acid rain. Other atmospheric degradants include ozone and oxides of nitrogen and sulfur. Changes in temperature and humidity may result in cracking, which arises from the expansion and contraction of coatings or substrates. Rates at which these processes occur vary, depending on exposure site(s), time of year, coating composition, and substrate.
