Nippon Paint Marine adds product tank protection to its self-indicating NOA range
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, the company said in its release.
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.
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. NOA60 HS is a superior grade pure epoxy formulated with special phenol-based resins to reinforce resistance to cracking especially on welds, providing greater resistance to saltwater and cathodic disbonding. Applied in two coats at 160µm per coat, NOA 60HS meets all PSPC acceptance criteria for water and cargo resistance, adhesion, cathodic disbondment, pinholes and undercutting. It is easy to clean and has low emissions of volatile organic compounds. Suitable for multipurpose use, its enhanced resistance to freshwater and seawater has led to the system becoming the number one coating for ballast tanks and void space protection.
