New Product Announcement: Anti-Fouling Line
Earlier this year, global coatings company AkzoNobel launched a new anti-fouling hull coating line called “Intersmooth.”
Both coatings, Intersmooth 7200Si SPC and Intersmooth 7476Si SPC, are a part of the company’s International brand and are reported to feature self-polishing silyl methacrylate technology.
“At AkzoNobel, we are committed to helping the marine industry reach its carbon neutral ambition—through continually developing products and services which contribute towards and boost financial returns in a sustainable way,” said Christopher Birkert, Global Marine Segment Manager. “The Intersmooth range has been trusted by our customers since 1974 and has had over 47,500 applications globally since its launch.”

Using a resin technology coupled with a biocide package, the Intersmooth 7200Si SPC coating has been further optimized and aims to provide cost-effective performance through its ability to reduce waste and VOC emissions, all while improving application efficiency.
The coating is noted to have benefited using higher solids and has a guaranteed speed loss threshold of 2.5%, according to the company. AkzoNobel adds that the formulation features an optimized biocide package that not only delivers a clean hull but helps operators contribute further to reach their environmental goals by reducing CO2 emissions in service.
It is also designed to provide less sensitivity to time and temperature in its service period and a reduced risk of surface cracking versus silyl acrylate-based products.
“By building on this solid technology, Intersmooth 7200Si SPC offers the best fuel savings for its class with its self-polishing technology delivering a low-friction underwater hull surface that contributes to an average speed loss of no more than 2.5% during 60 months in service,” said Birkert. “This delivers significant cost savings in application and operation over the scheme lifetime which can extend to 90 months.
“The latest advance in anti-fouling performance with our market-leading silyl methacrylate polymer technology demonstrates our commitment to delivering sustainably focused products and services that provide a step change opportunity for operators both economically and environmentally.”
Intersmooth 7476Si SPC
Serving as a second self-polishing silyl methacrylate product, Intersmooth 7476Si SPC also made its way to AkzoNobel’s anti-fouling line. According to reports, the coating aims to deliver consistent, reliable and industry leading antifouling performance over the dry-docking cycle through its ability to deliver a more consistent polishing rate that enables custom-designed schemes for vessels based on their predicted routes, to ensure they perform at their best—resulting in less interruption or delays in service.
Not only is the anti-fouling coating noted to deliver maintenance and cost savings to operators, but it also provides less sensitivity to time and temperature in its service period and a reduced risk of surface cracking.
“The high-performance, self-polishing, anti-fouling hull properties of Intersmooth 7476Si SPC can help operators meet these goals while delivering significant cost savings over their lifetime, which can be up to 90 months,” said Birkert, adding that the product can be used at both newbuilding and repair and provides a guaranteed clean hull over 45 static days, with a speed loss threshold capped at 1.4%.
“As a result,” he says, “it contributes to a reduction in operational and maintenance costs to improve fleet profitability.”
