Chen Liu. Development of Anti-fouling Coating Using in Marine Environment.  International Journal of Environmental Monitoring

The marine organism attaching to the ship hull would slow down the ship and increasing fuel consumption. In order to prevent the problem, anti-fouling paints are used to coat the bottoms of ships. At the same time, the harmful environmental effects of these paints such as tributyltin have been recognized. The International Convention on the Control of Harmful Anti-fouling Systems on Ships was adopted by the IMO in 2001 to prohibit the use of harmful organotins in anti-fouling paints used on ships. As the invention entered into force internationally, the most important work is to develop new material to replace the traditional coating. In this work, we summarize the development of anti-fouling paints all over the world and introduce the progress of the latest research.

There is need to optimize testing protocols for marine coatings and develop improved accelerated test systems that best simulate the erosion process on marine paints as ships travel. The selection of a marine environment with aggressive biofouling conditions is necessary to obtain early results on the performance of experimental antifouling coatings. Simulation of the erosion of the coatings on the hull is an important tool in evaluating the efficacy of novel formulations.
Procedures in marine exposure testing, criteria in the selection of ideal sites with aggressive fouling conditions and a proposal for a modified dynamic test system are described.
