IN FOCUS


A ship is at its fastest and most efficient with a freshly cleaned hull


resin base, reinforced with glass platelets (a typical application of two coats of 500 µm dft create a barrier of approximately 300 layers of glass platelets). After re-floating the coating is conditioned to an exceptionally smooth finish, with hull roughness brought down to a figure of less than 20 microns. The effectiveness of the coating against


fouling depends on regular in-water cleaning, which is possible due to the strength of composition. Unlike other coatings such cleaning is allowed by most ports due to the absence of biocides. Being a Hard coating, Ecospeed comes with a 10 year guarantee and is expected to last the lifetime of the vessel. Speaking at the Green Ships Technology


conference, Hydrex owner Boud Van Rompay said: “Any ship captain knows that his ship is at its fastest and most efficient with a freshly cleaned hull. We definitely see Hard coatings as the way forward for shipping”. International Paints recently announced two


new coatings, one traditional anti-fouling and one biocide-free coating. The new Intercept range is a biocidal linear


polishing polymer antifouling, using their LUBYON® polymer technology to provide a superhydrophilic surface. International promise in-service periods up to 90 months, and claim an average fuel consumption and associated emissions savings of 5% annually compared to typical controlled-depletion polymer antifoulings. The LUBYON coating swells on contact with seawater, helping to smooth out imperfections. The biocide release rate is largely unaffected by seawater temperature. International’s biocide-free Intersleek range is a


fluoropolymer coating designed to operate even when slow or ultra-slow steaming. Paul Robbins, Marine Marketing Director at International Paint said: “Amid record high


bunker fuel prices and lack of liquidity within the shipping industry, the economic importance of underwater hull condition cannot be understated. The launch of Intercept®8000 LPP and Intersleek®1100SR, demonstrates our commitment to providing customers with real choice and the broadest range of fouling control solutions that meet the specific needs of their vessels, fleets and operational preferences, while also supporting our commitment to sustainability.” Janssen PMP, a subsidiary of chemical giant


Johnson and Johnson, have recently released ECONEA, promoted as the first copper-free marine anti-fouling agent. ECONEA is a water- based ablative antifouling which also replaces most of the noxious solvents found in traditional antifouling paints with water. As a consequence of the absence of copper, ECONEA coatings are compatible with substrates including aluminium. ECONEA uses zinc compounds and an arylpyrrole compound (an analgaesic and anti- inflammatory agent which acts on the nervous system) as its biocidal constituents. ECONEA has been approved as an antifouling


preservative by the United States Environmental Protection Agency since 2007 (EPA Reg. No. 43813-27 and 43813-52). West Marine, the largest specialty retailer of boating supplies and accessories in the US, recently announced at the Miami International Boat Show in February this year that ECONEA-based CFA Eco antifouling paint is the winner of their fourth annual Green Product of the Year Award. ECONEA is supported as a new active


substance under the European Biocidal Products Directive and -Regulation for Product Type 21 (Antifouling Products). Tony Kempen, Product Manager, Marine Antifouling & Microbial Control for Janssen PMP, who gave a technical presentation at the European Coatings
