Nippon Paint Marine has added to its NOA range of self-indicating epoxy coatings with a new system specially developed to protect chemical and product carrier tanks from corrosion and cargo contamination.

NOA PC 700, a phenolic/novolac-based epoxy, is resistant to a wide range of chemicals, solvents and petroleum products, including those containing xylenes, methyl ethyl ketone, methanol, caustic soda and LSA fuel oil.

Makoto Nakagawa, General Manager Sales and Marketing, Nippon Paint Marine Coatings, Osaka, said: “The addition of NOA PC 700 to our established NOA range significantly protects inner cargo tanks from corrosion while preventing cargo contamination. As with all our NOA coatings, application is self-indicating which enables the applicator to visually confirm the correct (wet/dry film thickness has been achieved during the application process. Correct film thickness is crucial to mitigating against corrosion risk to maintain ship structural strength.”

Since the 1998 market launch of the first NOA (Nippon Optimised and Advanced) coating system, Nippon Paint Marine has introduced a number of different NOA products. And while each one is designed according to the anti-corrosive requirements of different parts of ship, all the coatings are based on pigments that have various opacities depending on film thickness.

“Achieving correct film thickness, especially on edges and corners, is a challenge but this remarkably simple concept allows shipyard staff, surveyors and coatings inspectors to literally see when the coating has been correctly applied. If the coating appears transparent, then film thickness is incorrect. When it is opaque, correct film thickness has been achieved,” said Nakagawa.

Hiro Yamashita, Technical Manager, Nippon Paint Marine (Europe), added: “While NOA application improves coating quality and helps to reduce manhours and costs, the coating system is fundamental to maintaining structural integrity. This is becoming more and more apparent with the increase in areas requiring coating and the reduction in the availability of skilled applicators.

With the introduction of NOA PC 700, Nippon Paint Marine hopes to emulate the market success of its NOA60 HS product, which has been applied to the ballast tanks of more than 1,300 newbuild vessels since its introduction in 1998.
