The development of antifouling paints is based on three concepts that are high performance/excellent durability, energy saving/laborsaving, and environmental protection, especially marine environmental protection. The International Convention on the Control of Harmful Anti-fouling System on Ship (the AFS Convention) entered into force on September 17th, 2008, and International Convention for the Control and Management of Ship's Ballast Water and Sediments (Ballast Water Convention) adopted in 2004. As the Transfer of Invasive Aquatic Species through Biofouling of Ships, regulations have taken more notice and are starting to take action. Moreover Copper Oxide Ecological Risk Assessment has been discussed. And also we concern VOC regulation, Hazard and Risk Assessment for Biocides assessed by PEC/PNEC. The concepts of marine paints are long-term durability, energy saving, labor saving, and environmental protection. The products are developed in the consideration of high performance coating/excellent durability for ship operator. Since vessels are traded and anchored in diverse environments, no single antifouling system technology is perfect for all vessel types. Each antifouling system has its own advantages and disadvantages. The antifouling systems introduced at this session still require further development to achieve biocide-free or low risk systems assessed by PEC/PNEC. Without resorting to a single antifouling technique, a large range of research is important. Recently silicone foul release coatings get a lot of attention due to fuel saving, biocide free, less maintenance cost, etc. On the silicone foul release coatings, marine growths have difficulty settling and are easily detached due to the paint film's low surface energy. Adjusting the surface energy of silicone coatings prevents adhesion of marine organisms. A silicone coating has an extra smooth surface and greater elasticity.
