Nippon launches new antifouling technology

(Posted on 17/02/21)

Leading coatings manufacturer Nippon Paint Marine has launched a new antifouling technology which enhances antifouling performance to a level and consistency never seen before. It also substantially improves the time and the film thickness required for application, compared to other hull coatings.

Introduced to the market this week, FASTAR is a self-polishing antifouling paint that incorporates a unique nano-domain resin structure designed to minimise the effect that seawater temperatures, vessel speeds and other external factors have on coating performance.

It is by precisely controlling the release of biocides that Nippon Paint Marine has been able to deliver a high-performing AF system with lower polishing rates.

Generally, antifouling performance becomes less reliable when its polishing rate is low. This is not the case with FASTAR.

The resin’s nano-domain structure which derives from the micro-domain structure used in Aquaterras – the world’s first biocide-free self-polishing hull coating – allows antifouling components to be accurately delivered and released in a much more precise, controlled and effective way.

Commenting on the ground-breaking development, Hirokazu Kaji, General Manager, Nippon Paint Marine, R&D, said: “We set up a unit dedicated to developing new resins and finding ways of providing better antifouling performance. After several years, a lot of trial and error and a huge amount of lab testing, research has borne fruit with an entirely new type of SPC antifouling technology.

“In addition, thanks to the reduced film thickness, shipowners applying FASTAR will benefit from shortened in-dock application and drying times, resulting in further cost savings.”

FASTAR’s required total minimum drying time at drydock for a large container vessel, for instance, is reduced by maximum 37%, compared to the length of time needed for other typical coating systems, depending on the actual ambient temperature during application.

Makoto Nakagawa, Marketing General Manager, Nippon Paint Marine, said: “FASTAR is an advanced self-polishing antifouling paint. Every aspect of its AF performance has been improved. No other paint maker has this technology. Its performance in both static and dynamic conditions is unrivalled.”

He added: “Shipowners demand effective and predictable performance from their antifouling systems in whatever sea conditions their vessels operate. FASTAR delivers that, while reducing overall capital and operational expenditure. It offers precise, predictable performance.”

While the cost benefits of the FASTAR system vary depending on vessel size and operational profile, typically less paint is required to protect a ship’s hull than existing SPCs.

FASTAR, Nippon Paint Marine’s 4th generation antifouling system, is available in four main versions – FASTAR I & II and FASTAR XI & XII, of which the latter two products incorporate Nippon Paint’s hydro-gel technology.

Nippon Paint Marine says the optional addition of the hydro-gel will give FASTAR XI & XII the same 8% reduction in fuel consumption and CO2 as the company’s proven A-LF-Sea series, which has been applied to more than 3,300 vessels since market introduction.

Nippon Paint Marine is now rolling out the new product for wide maritime application.
