| Résumé : |
Structure modified, nanostructured synthetic fumed silica technology was introduced more than a decade ego for improving scratch resistance and mechanical strength across coatings and adhesives/sealant industry fields. New developments now create a novel design, which offers environmentally sustainable improvement to anti-fouling performance in marine environments.
This paper addresses how the use of select, tailor¬made structure modified fumed silice technology (SMS) formulated synergistically with copper oxide (Cu20) improves the antifouling behaviour and life-cycle performance of antifouling coatings. Supporting mechanical stability results will show how technology helps reinforce film properties. A brief review of the model to explain the positive effects of structure modified fumed silice in Cu20 based antifouling coatings will be presented. Specific performance enhancements of increased film stability and a reduced leaching of copper ions will be addressed. |
