Algal disfigurement and degradation of architectural paints in India / C. D. Joshi in PAINTINDIA, Vol. XLVII, N° 1 (01/1997)

Titre : Algal disfigurement and degradation of architectural paints in India Type de document : texte imprimé Auteurs : C. D. Joshi, Auteur ; Usha Mukundan, Auteur Année de publication : 1997 Article en page(s) : p. 27-32 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Peinture Bâtiment 'Dégradation biologique' Feuil Algae Bioencrassement Adjuvant Biocide Thallophyta Index. décimale : 667.9 Revêtements et enduits Résumé : A great variety of algal genera have been implicated world-wide in the defacement and degradation of architectural paints, whether exterior or interior. This algal growth, particularly in the tropics, contribute to slow deterioration of structures, besides causing loss to the cosmetic and aesthetic appeal of the buildings, thus making early repainting necessary, which results in the increase of maintenance cost. These financial implications have led to the development of newer architectural paints resistant to excessive microbial biofouling. The efficacy of added biocides depends on minimum inhibition concentration required to inhibit the growth of individual alga and hence it is very essential to study the complete profile of algae attacking the architectural paints.

The results indicate that it may also be effective at reducing the early stages of biofouling, such as the attachment of bacteria that lead to a biofilm. In this study, the ability of zosteric acid in reducing the early stages of fouling was evaluated using attachment studies of fresh water bacteria via two approaches. First, plain coatings were submersed in water containing zosteric acid and either enriched Lake Erie bacteria or Pseudomonas putida, a model fresh water bacteria. It was found that zosteric acid with a concentration one-tenth of its EC50 (the concentration eliminates 50 % of the bacteria) was able to reduce bacterial attachment by more than 90 %. The second approach incorporated zosteric acid into silicone coatings in the presence of a common solvent to achieve the slow release of zosteric acid ; such coatings were then subjected to the bacterial attachment. A -75 % reduction in bacterial attachment was found for 1 wt % zosteric acid entrapped Sylgard® 184, a model silicone coating, but the reduction only achieved ~55% for 1 wt % zosteric acid entrapped in a commercial silicone coating, RTV11.
