[article]  inPAINTINDIA > Vol. LXI, N° 3 (03/2011) . - p. 45-47 Titre : Sustainability meets efficacy : Culture-independent bacteria identification using modern molecular-biological methods Type de document : texte imprimé Auteurs : Monika Lamoratta, Auteur ; Frank Sauer, Auteur Année de publication : 2011 Article en page(s) : p. 45-47 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Bactéries -- Identification Contamination microbienne Développement durable Revêtements:Peinture Index. décimale : 667.9 Revêtements et enduits Résumé : There has been a trend for some time now in the paint and coatings industry for the supply of environmentally friendly product solutions and for sustainability in product development and the manufacture of modern coating systems. A publication by the Wissenschaftliche Dienste des Deutschen Bundestages (scientific services of the German Bundestag) from 2004 describes the so-called threepillar model of sustainable development which is based on the idea that sustainable development is only achievable if environmental, social economic and social effectiveness of a society. The three aspects are mutually interdependent.

hectorite clay - a unique, multi-purpose rheological additive / Wouter Ijdo in PAINTINDIA, Vol. LXI, N° 3 (03/2011)

[article]  inPAINTINDIA > Vol. LXI, N° 3 (03/2011) . - p. 48-52 Titre : hectorite clay - a unique, multi-purpose rheological additive : Part 1 - Chemistry and peoperties Type de document : texte imprimé Auteurs : Wouter Ijdo, Auteur ; Douglas N. Smith, Auteur Année de publication : 2011 Article en page(s) : p. 48-52 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Hectorite Revêtements -- Additifs Index. décimale : 667.9 Revêtements et enduits Résumé : Some of the earliest applications that utilize "clay" date back to antiquity. Clay tokens were used for record keeping pueposes, bricks were made from clay mud and clay pottery had a practical use as well as a decortive purpose. Other typical uses of clay minerals in ancient time were in applications such as bleaching, laundry, cosmetics, medicine, porcelain etc. Some of these uses are still relevant today. Although old, the sophisticated nature of these clay applications should not be underestimated. The ancient Maya blue pigment is perhaps a good example of early nanotechnology where clay is used to stabilize an indigo dye. An organic - inorganic surface complex is formed when indigo dye binds to the clay surface during pigment preparation. Unlike the dye alone, this combined clay-dye complex is remarkably stable and does not fade when exposed to harsh weathering conditions. Furthermore, the clay-indigo color is resistant to acids, bases, chemical solvents and does not biodegrade. Other pigment systems can be formulated for use in coatings based on such dye-clay complexes and as such might offer an environmentally friendly alternative next to pigments currently used in the coatings industry.
