International Paint boosts antifouling product line

International Paint has improved and expanded its range of antifouling coatings. The line up now includes products with higher solids volumes products. These need a lower number of coats per scheme and produce lower levels of overspray and reduced VOC emissions.

The range features International Paint's highest-performing self polishing copolymer antifouling, Intersmooth SPC, its economical option Interspeed and a blend of both technologies in the new Interswift products.

Leading the parade are Intersmooth 7460HS SPC and Intersmooth 7465HS SPC. These are hydrolyzing self-polishing copolymer antifoulings for deep-sea vessels featuring high volume solids and low VOC's. Patented copper acrylate technology delivers controlled chemical dissolution of the paint film, which ensures continued smoothing over long drydocking intervals. Predictable polishing enables specifications to be tailored to specific ship types and operational profiles, while thin leached layers allow simple cleaning and recoating at drydockings.

Intersmooth 7460HS SPC and Intersmooth 7465HS SPC provide fouling control for up to 60 months and share in the proven track record of Intersmooth SPC on over 15,000 vessels worldwide. The alternative Intersmooth 360 SPC and Intersmooth 365 SPC variants are specially designed for coastal vessels.

New Interspeed 6400 and Interspeed 6200 have been developed from controlled depletion polymer (CDP) based Interspeed technology, which has been successfully applied to over 11,000 vessels. These products provide an economical choice for up to 36 months in service.

New Interswift 6800HS, developed from self polishing Interswift technology, is a high volume solids, low VOC blend of copper acrylate SPC technology and rosin based CDP technology. Providing up to 60 months fouling control in service, performance lies between the high performance SPC antifoulings and the more economical CDP antifoulings.

"The careful combination of technologies in Interswift 6800HS produces an antifouling which has the CDP benefits of surface tolerance, high volume solids and an attractive cost base, together with the patented copper acrylate SPC attributes of polishing rate control, reduced leached layer size and control of biocide release," says Mike Hindmarsh, Business Development Manager for Biocidal Antifoulings.

Also available is Interswift 455FB, a product designed for the unique fouling challenge experienced on flat bottom areas.

As well as combining technologies in a single product, a new "Advanced Duplex System" utilizing both Intersmooth and Interswift products provides high performance, cost effective fouling control options.
