[article]
Titre : Les plastiques s'adaptent aux techniques de stérilisation Type de document : texte imprimé Année de publication : 1999 Article en page(s) : p. 35-37 Langues : Français (fre) Tags : 'Industrie matière plastique' Thermoplastique 'Application médicale' 'Stérilisation thermique' Additif Antibactérien 'Etude marché' Index. décimale : 668.4 Plastiques, vinyles Résumé : Les matières plastiques répondent aujourd'hui de plus en plus à une demande de stérilisation quand le jetable n'est pas de mise. Et la stérilisation, c'est non seulement avoir une tenue à haute température mais aussi pouvoir combattre intrinsèquement les bactéries. Note de contenu : - Tenir à haute température

Titre : Technical considerations for formulating quality water based paints - microbiological view point Type de document : texte imprimé Auteurs : Girish A. Bhagwat, Auteur Année de publication : 1995 Article en page(s) : p. 27-34 Note générale : Bilbliogr. Langues : Anglais (eng) Tags : 'Peinture eau' Formulation 'Dégradation biologique' Bactérie émulsion' Feuil Adjuvant Antibactérien Fungi Algae Biocide Thallophyta Index. décimale : 667.9 Revêtements et enduits Résumé : This paper attempts to bring our salient features of microbes as potential deteriogens in water based paint systems and their manifestations.
With an accent on judicisouly controlling these defects in paints, the paint formulator is being appraised of various tools and techniques, which he may choose to exercise while formulating a quality water based paint.
Lastly, various factors which need to be considered before selection of specific preservatives are being discussed so as to derive the maximun cost benefit out of its usage.Note de contenu : CLASSIFICATION OF BIODETERIORATION IN LATEX PAINTS

Titre : Zosteric acid-an effective antifoulant for reducing fresh water bacterial attachment on coatings Type de document : texte imprimé Auteurs : Bi-min Zhang Newby, Auteur ; Teresa Cutright, Auteur ; Carlos A. Barrios, Auteur ; Qingwei Xu, Auteur Année de publication : 2006 Article en page(s) : p. 69-76 Note générale : Bibliogr. Langues : Américain (ame) Tags : Bactérie Pseudomonadales Pseudomonadaceae Zostérique acide Etude expérimentale Pseudomonas putida Adhérence Evaluation performance Cinnamique dérivé Sulfate organique Antibactérien Additif Siloxane polymère Protection antisalissure Biofilm Bioencrassement Matériau revêtement Index. décimale : 667.9 Revêtements et enduits Résumé : Zosteric acid, a natural product present in eelgrass, has been found to prevent the attachment of some bacteria and barnacles. 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.
