Promising approach for antifouling paints

Friday, 27 August 2010 | Posted by: Kirsten Wrede, European Coatings Journal

A sustainable life for the "inhabitants" of the sea - that's the overall goal of the "Marine Paint" research program. This project, carried out at the University of Gothenburg and Chalmers University of Technology in Sweden, is aimed at developing new and effective marine antifouling paints, which are more environmentally friendly than those in use today.

In the marine environment all surfaces are effected by the attachment of fouling organisms. According to the project managers, over 80,000 tons of antifouling paint are used every year in order to prevent fouling.

While there is an ongoing need to constantly improve the performance and cost efficiency of these systems, the rising environmental awareness as well as ever tighter legislation regarding safety and environmental protection are driving the development of eco-friendly marine coating solutions.

Now what's so exciting about the Swedish project? Sarting point is the discovery that treating a surface with medetomidine, which is used in veterinary medicine, is very effective for preventing fouling by barnacles. Thus the first phase of "Marine Paint" has been focused on the barnacles that are one of the major problems for shipping. Presently the scope of the research has been broadened to generate research results for a sustainable paint that could control all kinds of fouling organisms.

I think that "Marine Paint" is a step in the right direction, already showing promising first results.
