Due to the fact that Turkey is a country surrounded by seas, the paints used in marine vehicles become very important. It is necessary to control the emission limitations of antifouling paints containing Cu2O2 and it is foreseen that the use of eco-friendly antifouling paints that do not contain copper will be mandatory. The antifouling paint pigment used in marine vehicles will first be synthesized from national sources and thus the need in the antifouling paint market will be met. In this study, firstly, the synthesis parameters of phenyl fluoroborate, one of the special boron compounds were determined and then the usability of the obtained pigment in paint and its antibacterial properties were tested with the disc method. Phenol and fluoroboric acid were used as reactants in the synthesis of phenyl fluoroborate by wet method and H2SO4 was preferred as catalyst. Mole ratio of reactant ((n(C6H5OH) / n(HBF4)) = 1:1; 1,5:1; 2:1 and 2,5:1), temperature (30 degrees C, 35 degrees C, 40 degrees C, 50 degrees C and 60 degrees C) and reaction time that affect the reaction yield as synthesis parameters were investigated. FT-IR and BF4- ion selective electrodes were used for characterization studies. Phenyl fluoroborate was synthesized with 62% yield at a mole ratio of reactants of 2:1, 35 degrees C and 90 minutes. The pigment was converted into a solvent-based antifouling paint with an epoxy type binder and kept its paint form when immersed in sea water. Antibacterial activity was investigated using the agar disc diffusion method, and while the antibacterial property due to diffusion was not observed in the paint sample, the phenyl fluoroborate pigment showed antibacterial property.
