In recent years, there has been much demand for sophisticated marine coatings that comply with the
Performance Standard for Protective Coating (PSPC) for dedicated seawater ballast tanks in all type of
ships and double-side skin spaces of bulk carriers IMO/MSC/Res.215(82) and Cargo Oil Tank Coating
IMO/MSC/Res.288(87) as the mandatory requirements.
Conventional systems, such as sand blasting, for the secondary surface treatment used to remove the
contaminants produce dust that deteriorates the working environment and the abrasives (media) that
must be disposed as industrial waste.
