Utilization of microencapsulation is one approach to the delivery of biocides that has not been utilized in the mainstream of antifouling paint formulations. When formulating next generation paints that utilize hydrophobic nonmetallic biocides, it is necessary to develop an understanding of the release kinetics of the compounds from model polymeric coatings in order to better develop methods for providing long term efficacy.
The biocide 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one is a nonmetallic and nonenvironmentally persistent biocide that has been registered in several countries for use as an antifouling agent and has gained approval by the U.S. Environmental Protection Agency. The release characteristics of this biocide from copper microtubules as well as polymeric films were determined by high performance liquid chromatography.Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=5577

Titre : Dynamic simulations of a self-polishing antifouling paint exposed to seawater Type de document : texte imprimé Auteurs : Søren Kiil, Auteur ; Kim Dam-Johansen, Auteur ; Claus Erik Weinell ; Michael Pedersen (S.) ; Santiago Arias Codolar Année de publication : 2002 Article en page(s) : p. 45-54 Note générale : Bibliogr. Langues : Américain (ame) Tags : Autopolissage Protection antisalissure Modèle dynamique Simulation numérique Modélisation Libération Biocide Eau mer Navire Peinture Matériau revêtement Index. décimale : 667.9 Revêtements et enduits Résumé : A mathematical model for a self-polishing antifouling paint exposed to seawater was extended to handle dynamic simulations. The aim has been to investigate, quantitatively, the transient responses of the paint to changes in seawater temperature, pH, concentration of NaCl, and ship speed. The simulation study revealed that polishing and biocide release rates for a paint present on a ship bottom rarely reach stable conditions, because of the slow response of the paint to changes in temperature and ship speed. It was also found that the paint behavior stabilizes more rapidly from a temperature or speed increase than from temperature or speed reductions. These results are essential for the testing of paints on ships and useful information in the development of novel self-polishing antifouling paints. The modeling approach underlying the simulations can be applied to any type of self-polishing antifouling paint provided that sufficient kinetic, solubility, and diffusivity data are available for the pertinent rate steps influencing the paint behavior.
