Preliminary data from in vitro assays is frequently used to screen the performance of AF coatings. It is intuitive that microbial composition plays a major role in surface colonisation. The rationale behind this study is to investigate whether using a mixed population for the in vitro tests yields substantially different results than using single strains during initial screening. A polymeric coating was tested against single- and dual-species cultures of two common microfouler organisms for 49 days. A bacterium (Pseudoaltermonas tunicata) and a cyanobacterium (Cyanobium sp. LEGE 10375) were used in this study. Linear regression analysis revealed that Cyanobium sp. biofilms were significantly associated with a higher number of cells, wet weight, thickness and biovolume compared to dual-species biofilms. P tunicata alone had a biofilm growth kinetics similar to dual-species biofilms, although the Ptunicata-Cyanobium sp. mixture developed less dense and thinner biofilms compared to both single-species biofilms. Cyanobium sp. LEGE 10375 biofilms provided the worst-case scenario, ie, the conditions that caused higher biofilm amounts on the surface material under test. Therefore, it is likely that assessing the AF performance of new coatings using the most stringent conditions may yield more robust results than using a mixed population, as competition between microfouler organisms may reduce the biofilm formation capacity of the consortium.

Traîtements de surfaceIndex. décimale : 667.9 Revêtements et enduits Résumé : Surface preparation metrics for marine coatings - Protective coating systems provide the primary corrosion protection for assets in sea water. They are defined as a specific combination of surface preparation and coating material applied under specified conditions to a specific structure. Over many years, the paint industry has focused considerable resources toward the formulation, performance testing and fine tuning of coating materials. These efforts have produced outstanding results through implementation of advancements such as single-coat, ultra-high-solids paint for tanks, and by sharpening and implementing aggressive requirements in quality assurance and specification documents. Far less emphasis has been placed on understanding and refining the details of surface preparation and the effects of variations in these details on the subsequent performance of sea water immersion coatings. However, it is generally accepted that improper or inadequate surface preparation is a major contributor to real-world coating failures. Note de contenu : TABLE 1 : Grits tested

ToxicologieIndex. décimale : 667.9 Revêtements et enduits Résumé : Antifouling is the process of removing or preventing the accumulation of marine organisms from the surface of hull and the paint used for this application is called anti fouling paint. Marine biofouling is of major economic concern to ail marine industries. The shipping trade is particularly alert to the development of new antifouling (AF) strategies, especially green AF paint as international regulations regarding the environmental impact of the compounds actually incorporated into the formulations are becoming more and stricter. It is then crucial to develop new AF solutions combining advances in marine chemistry and topography, in addition to acknowledgement of marine biofoulers, with respect to the marine environment. This review presents the recent research progress made in the field of new non-toxic AF solutions (new microtexturing of surfaces, fout-release coatings, and with a special emphasis on marine natural antifoulants) as well as the perspectives for future research directions.

SiliconesLes silicones, ou polysiloxanes, sont des composés inorganiques formés d'une chaine silicium-oxygène (...-Si-O-Si-O-Si-O-...) sur laquelle des groupes se fixent, sur les atomes de silicium. Certains groupes organiques peuvent être utilisés pour relier entre elles plusieurs de ces chaines (...-Si-O-...). Le type le plus courant est le poly(diméthylsiloxane) linéaire ou PDMS. Le second groupe en importance de matériaux en silicone est celui des résines de silicone, formées par des oligosiloxanes ramifiés ou en forme de cage (wiki).Index. décimale : 667.9 Revêtements et enduits Résumé : With emerging regulations and restrictions concerning the protection of environment and human health a great transformation is taking place in the coating industry for marine application with research focused on reducing the VOC content and the use of carcinogenic and toxic components in the coating. This review focuses on recent developments in non-toxic antifouling coating for marine application based on silicones and thus summarizes potential substitutes for the conventionally used eroding paints which effect the ecological system. Coating systems like polyorganosilazane—silicone, PDMS/PMMA copolymer, amphiphilic surface coating based on PEO-silane tether segments and PDMS and Zwitterionic siloxane-polyurethane are discussed in this article. The Zwitterionic siloxane- polyurethane system mentioned includes poly(SBMA)-block-PDMS-block-poly(SBMA) triblock polymer incorporated in a polyurethane formulation and carboxybetaine functionalized polysiloxanes (PDMS-g-CB). The characterization and properties of the coating systems are discussed in detail along with comparison and reasoning for their potential use as anti-fou ling or fouling-release coating for marine application.

TriazolesLes triazoles sont des composés organiques cycliques comportant un cycle à 5 atomes, comportant deux double liaisons et 3 atomes d'azote et donc de formule brute C2H3N3. Elles sont aromatiques et font partie des cycles excédentaires en électrons.
Selon la position des atomes d'azote, on distingue les 1,2,3-triazoles (appelées V-triazoles) et les 1,2,4-triazoles (appelées S-triazoles). (Wikipedia)Index. décimale : 667.9 Revêtements et enduits Résumé : 4-Amino-3-hydrazino-5-thio-1,2,4-triazole (1), its copper complex, and its chlorinated derivatives have been synthesized and tested as antifouling and anticorrosive agents. The tests were carried out through the incorporation of the three compounds in different paint formulations, which were applied to polyvinyl chloride (PVC) and steel substrates. The coated panels were tested in Alexandria's western harbor's water.
