Abstract
The most effective commercially available antifouling paint system is based on organotin, which is chemically attached to a long chain polymeric binder. Environmental studies have revealed that the proportion of organotin in sea water near the shores has reached an alarming level. Therefore, attempts are being made in many directions to eliminate tin from antifouling paint systems. Design of a highly toxic copper based paint system is one of the latest areas of research.
In the present work, a copper complex based on carboxyl containing polymer has been synthesized. Paints were formulated using the complexes as pigment. Critical pigment volume concentration is found to be around 35%. Both accelerated and normal leaching behavior were studied. The release of copper from complex is slower and steadier compared to that from cuprous oxide. The later part of leaching is very close to steady-state behavior.
