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 aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Several solvent- and water-borne exterior wood coatings were artificially weathered to study their performance behavior. Penetration and layer thickness were measured on unweathercd samples and compared to theoretical estimates by means of measured basic parameters of coating and substrate. Color, surface roughness, gloss, and adhesion were monitored during aging, and the latter two were also calculated and compared to their experimental values. Theoretical values of gloss, and especially those of adhesion, were less successful on an absolute scale, but were in accordance with practical values on a relative scale. The influence of solid content, drying speed, and viscosity on penetration depth manifested itself clearly both in theory and in practice. In general, solvent-borne coatings performed well, but some water-borne coatings also showed good performance. By measuring the characteristics of a coating as described in this article, it is possible to rank the coatings and follow their weatherability. Finally, calculation of theoretical values proved a promising method for initial screening purpose.

Titre : Fungal disfigurement of exterior wood coatings : from subjective rating towards 3D/4D objectivity Type de document : texte imprimé Auteurs : Jan van den Bulcke, Auteur ; Joris van Acker, Auteur ; Imke de Windt, Auteur ; Marc Stevens, Auteur Année de publication : 2008 Article en page(s) : p. 18-23 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : The European Biocidal Products Directive (BPD) challenges the (wood) coating manufacturers to produce coatings with reduced amounts of biocides or even avoid using biocides. Moreover, coatings should also comply with the European VOC Solvents Directive, forcing the industry to switch to low/non-VOC constituents. Given this legislation, an integrated view on the interaction of coating-substrate-environment is essential if the performance of future coatings should enhance or at leat remain comparable adequate. Research concerning fungal deterioration of wood coatings is exactly in the scope of such an approach. In this work a modified version of the European standard blue stain test for coatings (EN152) is presented which is further complemented with testing in a contrallable environment, the so-called Fungal Control Unit (FCU). This test setup combines the advantage of accelerated artificial wethering, biological deterioration and mimicry of the outdoor situation. Both additional tests give complementary information on fungal susceptibility linkin them with outdoor infestation. Samples are analysed in 3D to acquire in-depth knowledge on fungal growth. In addition, 3D/4D X-ray sub-micron tomography and accompanying image processing is illustrated as a powerful non-invasive technique for coating research, visualizing at the same time coating, wood and fungus and linking their characteristics. Ultimately, combining fungal growth data with physicochemical information of the coating (film formation, UV degradation...) and wood (water absorption, nutrient content...) should lead to cyberfungal deterioration modelling in 4D supporting manufacturers in the development of the innovative 'green' coating.

PolydiméthylsiloxaneLe polydiméthylsiloxane —[O-Si(CH3)2]n—, ou poly(diméthylsiloxane) selon la nomenclature systématique, communément appelé PDMS ou diméthicone, est un polymère organominéral de la famille des siloxanes souvent présent dans les shampoings. On l'y ajoute pour augmenter le volume des cheveux mais il peut également aller boucher les pores du cuir chevelu et rendre les cheveux gras. C'est une des raisons pour lesquelles se laver les cheveux tous les jours est très déconseillé avec un shampooing contenant des silicones.
Il existe également de l'amodiméthicone, qui est un dérivé du diméthicone.
Le polydiméthylsiloxane est un additif alimentaire (E900), utilisé comme antimoussant dans les boissons (Coca-Cola BlāK).
La chaîne de poly(diméthylsiloxane) forme également la structure de base des huiles et des caoutchoucs silicones.Index. décimale : 667.9 Revêtements et enduits Résumé : An EU-funded project seeks to demonstrate that treatments with silicon-based hydrophobisers can protect exterior wood against water penetration, extend its service life and so potentially minimize the use of biocides. Both brush and vacuum impregnation processes showed significant levels of protection and a reduction in water pick-up. Note de contenu : - Five impregnating materials tested
- Wood specimens and application test protocols
- Vacuum process pick-up depends mainly on wood type
- Details of water repellent application by brushing
- Application methods and products compared
- Significant protection against wood damaging fungi
- Partial protection against subterranean termites
- Field testing confirms differences in water pick-up
- Significant though variable benefits achieved
