Ballast Tank Coatings


Ballast tanks are areas of complex steel structure with poor access and permanent condensation.

The application of conventional paint systems in sea water ballast tanks can lead to many problems; shrinkage, porosity, becoming brittle with age, bad edge and weld coverage. Conventional paint systems additionally have extensive equipment requirements. Soft coatings are also no longer acceptable due to changes in IMO regulations.
