Who wants algae, animals and micro-organisms to “decorate” the hull of ones boat? Not the owners of recreation boats and not the large shipping companies, because it costs money! But all these actors are environmentally conscious and want to use anti-fouling paints that reduce fouling without destroying marine environment. The MARINORD project will develop such anti-fouling paints containing nano-particles filled with active substances.

Traditionally, marine fouling has been prevented by the addition of heavy metals compounds, but these have had negative effects on many organisms in the sea and have therefore been banned. Instead, copper is widely used as antifouling agent in marine paints. However, copper is also now suspected of being harmful to the life in the sea at the same time as its price is rising.

The project group of MARINORD will use alternative anti-fouling agents and work with nano-particles in order to develop eco-friendly and cheap anti-fouling paints. Paint contains many ingredients that have to be compatible with each other and still fulfil their function. This is where the nano-technology will play its role, by making it possible to mix important ingredients (binder and active substances) that would not be mixable otherwise. By releasing the active substances in a controlled way, these new paints will still have an anti-fouling effect many years after painting a boat hull.
