A new coating developed to deliver greater protection to bulk carrier cargo holds has gained considerable market acceptance with almost 40 applications since its official introduction in August last year.
Nippon Paint Marine’s new Neoguard Toughness has already been applied to the holds of 37 bulk carriers operated by various owners.
“We developed Neoguard Toughness following demand from shipowners for a more impact-resistant epoxy coating system for holds and hatch coamings, but we didn’t expect to have quite as many applications so soon after market launch,” said Nippon Paint Marine Marketing General Manager Makoto Nakagawa.
“Neoguard Toughness is undoubtedly one of the hardest, toughest coatings we have produced for the commercial marine market.”
The thickness of the highly solid epoxy coating is particularly suited to protecting steel structures from abrasion and impact damage from iron ore, coal, and other bulk cargoes, while providing long-term protection against corrosion. The product satisfies the requirement of the U.S. FDA for compatibility with grain and feed.
“Mechanical damage to cargo holds from abrasive cargoes and high impact loading procedures is the primary reason traditional coatings fail, which if goes unchecked can lead to corrosion and structural failure. Neoguard Toughness reduces this risk,” said Nakagawa.
Resistant to cracking from impacts of up to 4 joules, the hardened paint is applied to achieve a dry film thickness of 250µm. No special equipment or machinery is required for application; the coating is applied using a conventional air spray, with a full cure dry taking 5 days at 30°C.
Commenting on the coatings performance, Ahmet Hamza, General Coordinator at Iskenderun Shipping, which in November applied the coating to the holds of the 32,676dwt Iskenderun M, said: “So far so good. We have found Neoguard Toughness offers significant cost savings by reducing the maintenance and repair requirement. The coating's easy cleaning properties have also allowed for quick and efficient turnaround times between cargoes.”
While hold cleaning and reduced maintenance are obvious benefits, Nippon Paint Marine Director John Drew added that the toughness of the coating can mitigate against port delays following failed cargo hold inspections.
“Neoguard Toughness significantly improves the chances of passing inspection. The coating enables ship owners to keep their cargo holds in excellent condition,” he said.
These photographs of Neoguard Toughness applied to the cargo holds of a bulk carrier were taken five months after application. The vessel had been carrying coal cargoes, which are typically aggressive to coatings
About Nippon Paint Marine
Nippon Paint Marine is a subsidiary of Nippon Paint Holdings, a top five global paint supplier.
Nippon Paint has been producing marine coatings in Japan since the 1880s and has been the leader in the development of all kind of marine paint technology but especially antifouling paints.
Nippon Paint developed and launched the world’s first self-polishing (SPC) tin-free antifouling paint in the 1990s and followed that by the launch of the world’s first low-friction SPC in 2006. More recently, the company developed Aquaterras, the world’s only biocide-free SPC antifouling paint. Aquaterras is a unique micro-domain SPC developed by Nippon Paint Marine from raw materials used in the pharmaceutical fields.
