The corrosivity and performance evaluation for antifouling paint exposed in seawater Muara Baru port, Jakarta

Antifouling paints are applied on a wide range of the under seawater structures in order to protect them from the growth of fouling organisms. The investigation of the performance for two commercial anticorrosion and antifouling paints was conducted in Muara Baru port, Jakarta. The specimens were coated by anticorrosive and/or antifouling paint. Blank specimen (without exposed) were also prepared as a control. On the other hand, bare mild steel was prepared for measure the corrosion rate throught weight loss method. The test panels containing specimens were exposed up to 3 months for immersion depths of 0, 1, 2, 3 meters from sea level. Sea water parameters such as temperature, pH, salinity, conductivity and dissolved oxygen (DO) were also measured. The evaluation of coating performance was carried out such as thickness, glossy, hardness and adhesion strength. The results show that both surfaces of anticorrosive paint and bare mild steel specimen covered by fouling organisms, whereas no fouling took place on the surface of antifouling paint. The corrosion rate of bare mild steel in the depths of 0, 1, 2, 3 meters are 12.5; 11.6; 8.3; 10.4 mpy,respectively. IOP Journal of Physics: Conference Series (JPCS) ISFAP 2016
