Abstract:

The kinetics of the process whereby copper ions toxic for marine organisms are leached from antifouling coatings of KHV-53 and KHS-79 paints were studied. It was shown that this process takes place at differing temperatures, chlorion concentrations and leaching medium pH, and that it follows equal regular patterns for both paints temperature, however, is the most important factor determining the leaching speed of copper from coatings. It is recommended that a fast method of determining the effectiveness of antifouling coatings be used employing a glycine solution it is essential that the samples being tested be thermostatically controlled and rotated in the leaching medium. An improved quick method has been developed for determining the leaching speed of copper from antifouling coatings in a thermostatically controlled apparatus. This method is suitable for checking the efficiency of antifouling paints both when paint formulas and coating systems are being developed and when the quality of industrial output is being inspected.
