SeaLion Fouling Release Coating

Jotun Coatings have launched new SeaLion fouling release coating (FRC). This silicone-based elastomeric coating provides a smooth, non-stick, water-repellent and self-cleaning surface. According to the company, the smooth surface will result in less fouling of hulls, propellers and rudders, which will ultimately lead to improved vessel performance and fuel benefits. By comparing SeaLion with most TBT-free antifoulings over a 10 years perspective, fuel savings in the order of 1.5 percent are estimated by the company.

It's not only the fuel costs that are reduced by this new coating. The vessel will also need less paint. Often up to 40 percent of a silicone FRC can be lost into the atmosphere on application while with this new paint lower volumes are lost thanks to reduced dry spray. SeaLion is particularly suitable for fast moving and high activity vessels. The coating keeps hulls, propellers and rudders free from fouling and provides a smooth surface for at least 60 months. The fouling attracted to the vessel whilst stationery or slow moving is removed when the vessel is in motion. Generally, silicone based elastomeric coatings are less hard than traditional TBT-free antifoulings. SeaLion dries faster than other similar coatings, which reduces the risk of damage. Whilst care must normally be taken to avoid scraping or scratching this type of product, the coating provides a cushion effect that offers good protection against bumps.
