This paper outlines the development of 1:1 plural-component, rapid-cure, edge retentive, 100% solids, rigid and structural polyurethane coatings technology for corrosion protection of ballast tanks. It highlights not only the advantages but also the challenges of the use of the coatings technology in the ballast tank application in terms of coating's edge retention, substrate surface and environmental conditions, application techniques and equipment requirements. The paper discusses case histories and experiences of the coatings technology in several ballast tank applications to highlight these challenges and resolutions.
