XénonIndex. décimale : 667.9 Revêtements et enduits Résumé : As an external laboratory testing our formulations and customers’ samples, we perform weathering tests in a UV or xenon chamber, and the client, after receiving the report, will often ask "why is there no real world equivalent years?" In this article, we answer why there are no and will not be such conversion factors.
This article is intended to be a kind of guidance for project participants related to determining the durability of coatings assessed against accelerated artificial weathering using laboratory chambers. We want it to be a publication to be quoted for both our clients and others who often face such a question and do not have a clear answer.Note de contenu : - In what cases are weathering & lightfastness test used ?
- The correct course of exposure of coatings
- Correlation of exposure in the chambers to natural conditions

Titre : Accelerated corrosion protection tests : Laboratory testing devices Type de document : texte imprimé Année de publication : 2010 Article en page(s) : p. 54-55 Langues : Anglais (eng) Catégories : Acier L'acier est un alliage métallique utilisé dans les domaines de la construction métallique et de la construction mécanique.
L'acier est constitué d'au moins deux éléments, le fer, très majoritaire, et le carbone, dans des proportions comprises entre 0,02 % et 2 % en masse1.
C'est essentiellement la teneur en carbone qui confère à l'alliage les propriétés du métal qu'on appelle "acier". Il existe d’autres métaux à base de fer qui ne sont pas des aciers comme les fontes et les ferronickels par exemple.

Revêtements organiquesIndex. décimale : 667.6 Peintures Résumé : Dispersion or emulsion paints are formulated with a variety of chemically different types of binders, which in most cases can be classified as acrylic esters copolymers or vinyl ester copolymers. A suitable binder is necessary to give a high quality paint. Experiments on masonry paints in the PVC range of 35 to 55% show that after many years of outdoor exposure no significant difference between straight acrylic and acrylic/styrene copolymers can be found. More important is the optimisation of the pigment volume concentration and the pigment/extender combination than the type of the binder.

- Water is the main source of damage a coating
- Neutralisation of binders with NaOH gives better WA and WVTR results

- Colour changes due to outdoor exposure

Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Wood is a renewable material that has been recognized for a long time as a valuable material for construction and engineering. Sound, solid wood can last for centuries. Nevertheless, wood is susceptible to biological and physical degradation. Therefore it needs to be protected properly, all the more when using less durable species. A variety of finishes can be applied. These coatings must meet certain minimum requirements, among which are sufficient penetration, resistance to physical and biological discoloration, and good adhesion. The last is considered the utmost important factor for the overall performance of a coating. Without an adequate anchoring to the wood, the coating will peel off prematurely and, thus, affect the lifetime of the substrate. In this article, the impact of the type of coating used, the wood species, and preweathering of the wood on adhesion are disclosed. In addition, the effect of weathering on the wood-coating system as a whole is looked at as well. The adhesion measurements were obtained with a mechanical torque device developed at VTT in Finland.

Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Using a modified torque technique, statistically significant differences in adhesion values were detected for waterborne model paints on wood as a function of moisture content, waterborne preservative, and after fungal inoculation. Change in a paint constituent sometimes resulted in a significant change in the adhesion value. The adhesion values of the alkyd emulsion paints tested decreased after inoculation with a blue stain fungus. On the contrary, the adhesion values of the acrylic dispersion paints tested became significantly higher after inoculation. Note de contenu : - Painted wood samples
- Waterborne paints
- Inoculation with a blue stain fungus
- Preservative treated samples
- Measurement of adhesion
- Further assessment of the samplesPermalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=17965
