EcoFleets' polishing mechanism derives from a combination of chemical and physical reactions of the coating after immersion with seawater. These effects occur in synchrony to release biocides from the film and in so doing the film thickness is sequentially reduced – the process referred to as polishing.

Sigma EcoFleet antifouling coatings also have extra co-biocides to improve fouling resistance, particularly against algae. Its film properties are good and 2-3 coats can be specified at dry film thicknesses up to 150 µm. The leached layer is more controlled, and typical projected service lifetimes are up to 36 months for deep sea vessels, with up to 60 months possible for certain situations / operating conditions.

The Sigma EcoFleet antifoulings portfolio has products designed for high, medium and low activity vessels, giving you a flexible, dependable, service-predictable solution for both newbuilding and maintenance and repair ships. The range offers products suited to deep sea- as well as coastal-operating vessels and for every market from fishing vessels to tankers, bulk carriers and container ships.
