Marine anticorrosion paints based on thiouracil compounds
- National Inst. of Oceanog. & Fisheries, Alexendria (Egypt)
The inhibition of marine corrosion of steel by 6-amino-2-thiouracil (1) and its derivatives 6-benzylideneamino-2-thiouracil (2) and 6-p-chlorobenzylideneamino-2-thiouracil (3) has been tested on laboratory scale using electrochemical technique which was performed on mild steel in sea water medium and on field scale through the incorporation of the compounds individually in marine paints compositions. The paint containing the compounds were applied on unprimed steel and the coated panels were tested in Alexandria Eastern Harbour water (Egypt). The electrochemical measurements indicate that both compounds (1) & (3) act as cathodic-type inhibitors, but the data of compound (2) showed neither cathodic nor anodic inhibition. The paint composition based on the soluble resin material as a sole binder and containing compound (1) showed the best corrosion protection of its steel surface tell more than 2 months followed by the paint composition containing compound (3). On the other hand, oil is not recommended with paint composition containing these compounds.
