New Resilient Coating for Hulls from Container Vessels to Cruise Liners

Latest Antifouling Product Claimed to Reduce Fuel and Maintenance Costs
Shipping News Feature

NORWAY – US – WORLDWIDE – Mention antifouling and one name immediately springs to mind, Jotun has been supplying merchant shipping with suitable coatings since moving into the marine paints market selling coatings to the whaling fleets in 1926 and now its products adorn the hulls of a multiplicity of vessels from container ships to supertankers. At this weeks Miami Cruise Shipping Exhibition (March 11-14) another new product has been unveiled which the company claims is a first in the hull protection field.

Following extensive research and testing, Jotun has introduced the industry’s first anti-fouling coating that includes epoxy-polysiloxane, a compound of resins and hardeners that provides highly resilient hull protection. Called SeaLion Resilient, when combined with Jotun’s proven Fouling Release Coatings (FRC) technology the epoxy-polysiloxane in SeaLion Resilient prevents settling of organisms on the hull and produces a glossy, smooth surface ideal for owners seeking to reduce costs related to dry-docking and maintenance.

Jotun says SeaLion Resilient has been specifically formulated for owners and managers seeking improved maintenance and docking efficiency. The properties of SeaLion Resilient significantly reduce the risk of mechanical damage and maintain hull condition throughout the service period. By simplifying maintenance and reducing need for repair, SeaLion Resilient can contribute to a significant reduction in off-hire time and docking and labour costs, while keeping paint consumption to a minimum.

In addition to the strong coating reducing mechanical damage, SeaLion Resilient resists fouling and provides a smooth surface that decreases drag and hence effecting carbon emissions by savings in fuel consumption. Requiring only two coats, Sea Lion Resilient is easy to apply and cuts time spent in dock, resulting in significant savings related to maintenance and repair.

Although and advance which Jotun believe will suit different classes of vessels initially the product is being aimed at the cruise market during the introduction in Miami this week whilst, consistent with Jotun’s sustainability programme (Jotun GreenSteps), SeaLion Resilient is a biocide-free coating and has low VOC emissions, making it a sustainable coating solution. Jorunn Saetnoe, Product Manager Antifouling, commented:

“We are confident that cruise ship owners will recognise the value of using a product that combines a glossy appearance with anti-abrasive qualities that effectively prevent most types of mechanical damage, and for owners operating Caribbean cruises, where warm and shallow waters contribute to rapid fouling, Sea Lion Resilient helps reduce costs related to underwater cleaning and cuts the risk of transferring of invasive species to highly regulated areas.”
