Jotun (Sandefjord, Norway) is billing a new antifouling marine-coating product—SeaLion Repulse—as a “major step” in foul-release technology. The company said the product, based on Jotun’s “Nanorepellent Technology,” is reported to possess both release and repellent properties. The product is targeted primarily at the cruise-ship market.
“Through nanoscale engineering. a repellent silicone layer is created on the surface,” the company said in announcing the product introduction. “The nano structures extend into the water and create a layer that acts as nano-scaled springs. When the spring-like structures are compressed, a counter force is developed. The nanoscale springs thereby provide release and repellent properties.” The result is a smoother hull surface and a coating-system lifetime of up to 10 years under normal conditions, the company said.
The product marks an expansion of Jotun’s existing antifouling-coatings technology portfolio; the company calls its silyl acrylate technology one of the industry’s most advanced antifouling coatings chemistries, with applications to more than 5,000 vessels since it was launched in 2000.
Jotun offers a range of products for cruise ships, including primers, topcoats, antifouling, and foul-release coatings for drydock and new-build applications. The company says 630,000 liters of its products have been applied to the world’s biggest cruise ship, Royal Caribbean International’s Oasis of the Seas.
