SAS Seawax Marine Coatings, of France, has introduced a water-based antifouling coating without solvents, silicon, Teflon or biocides.
Seawax Fouling Release and Seawax Etch Primer comprise a coating system based on an anti-adhesive film that the manufacturer says makes stable, durable microorganism attachment impossible. The film is self-cleaning when the boat reaches a speed of five knots, the manufacturer says.
The company calls the coatings “100% neutral” and says they contain none of the silicon, Teflon and biocides that will be banned as of 2014 by the European Community’s REACH regulation.
The products can be used on all sea boats and river boats, including iron and steel ship bodies, Seawax says. The coating is an insulator that enhances substrate water resistance, but it has no anti-corrosion properties. On iron and steel substrates, a layer of anti-corrosion coating should be applied first, the manufacturer advises.
Seawax Fouling Release is a fast-drying hydrogel recommended for use on boat hulls, Seawax says. The coating reduces weight and water resistance, while preventing or delaying the attachment of microorganisms, according to the supplier. The product must be re-applied every year.
Seawax Etch Primer must be applied before Fouling Release, the manufacturer reports. The primer is an “eco-designed,” single-component polyurethane resin that can be applied directly to the substrate or onto existing coatings.
