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.

However, especially with aqueous coatings, the resistance of corresponding films can deteriorate because of their hydrophilic structure. The aim of this study was to develop polymeric wetting and dispersing additives for aqueous pigment concentrates which display no significant negative impact on the corrosion protection of aqueous coatings. The polymers were produced using various polymerization processes and comparatively evaluated. Note de contenu : - Wetting and dispersing additives enable a productive dispersion process - Investigated wetting and dispersing additives - Production of the pigment concentrates - Test coatings - Test methods - Discussion of the results : Rheological properties of the pigment concentrates - Coloristic properties at the highest level - A new benchmark for corrosion resistance - Reduced water absorption improves resistance Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=20336 [article]
