International Paint has unveiled a new copper-free antifouling that has gained U.S. Navy approval for several applications.
Interspeed 5640 is a low-VOC antifouling that uses the latest non-metallic biodegradable organic biocides to deliver fouling protection of up to 36 months, the manufacturer reports.

The coating can be applied at newbuilding, maintenance or repair drydocking for major refurbishment or to upgrade/repair existing tin-free copolymers and tin-free ablative/CDP antifoulings.
With U.S. Naval vessels in mind, Interspeed 5640 was developed to meet—and has been approved for —MIL-PRF-24647 Type I Classes 1 & 2, Grades A & B, Applications 1 & 4. The coating is suitable for military vessels trading in US coastal waters and beyond, the company says.
The approval follows years of research dedicated to meeting the U.S. Navy’s stated aims of metal-free fouling control, International Paint said in a release.
“This approval now allows government specifiers and end users an alternative option for fouling control, particularly in areas where copper-free products are a prerequisite,” said John Mangano, Business Development Manager, International Paint Marine Coatings.
Features and Specs
Interspeed 5640 is acceptable for use on aluminum hulls and can be applied over existing copper-based antifoulings in good condition. The coating provides a durable film that is compliant in all locations that require <400 g/l VOC content. International Paint says the coating is easy to apply and leaves a smooth hull.
