International Paint has introduced Intersmooth7465Si SPC and Interswift 6900Si silyl acrylate antifouling coatings.

The manufacturer says it is the first and only supplier to offer both copper acrylate and silyl acrylate antifouling coatings in its range of fouling control technologies.

The coatings integrate International Paint’s silyl acrylate technology, patented in 2006 for use with products of <400g/l VOC.

The company patented silyl acrylate technology for use with products of <400g/l VOC in 2006. Now incorporated into Intersmooth 7465Si SPC and Interswift 6900Si, the technology allows the same performance as International Paint’s current Intersmooth 7460/5HS SPC and Interswift 6800HS copper acrylate antifouling coatings, the manufacturer says.

Both new silyl products have solvent emission levels of less than 400g/l VOC—among the lowest silyl acrylate solvent emission levels in the industry, International Paint says.

Features and Performance

Designed for deep-sea vessels at newbuilding and maintenance and repair, Intersmooth 7465Si SPC features 55% volume solids, allowing for faster application, less waste and pail consumption and lower solvent emissions than lower-volume-solids products, the manufacturer says.

Reduced overspray means lower contamination levels in dock and reduced applicator exposure. International Paint promises “predictable, high-performance fouling control for up to 90 months” (for vessels covered by the extended drydocking, or EDD, program) and “self-smoothing action” that “potentially reduces fuel use by 4%,” compared to self-polishing copolymer antifoulings with CDP or rosin-based antifoulings.

Also designed for vessels at newbuilding and maintenance and repair, Interswift 6900Si offers 61% volume solids, surface tolerance and in-service periods of up to 60 months with potential fuel savings of 1.5%, compared to self-polishing copolymer antifoulings with CDP or rosin-based antifoulings.

Fuel savings estimates are based on more than 5,000 vessel drydockings and inspections for fouling rating, combined with average hull roughness measurements from more than 50 vessel outdockings.

“We recognize that our customers have different requirements and operational preferences, which is why we offer a broad choice of fouling control products and technologies in our high-performance range,” said business development manager Mike Hindmarsh.

“Customers simply choose which technology option best meets their needs, and we deliver the performance.”

Will these 2 new Antifoulings work on tugs and fishing vessels?
