CSP antifouling
US-based PPG Protective and Marine Coatings has announced Sigma Sailadvance, a new range of high performance commercial vessel antifoulings suitable for a variety of operating conditions.
The range currently comprises four coatings, including Sigma Sailadvance RX and GX, two completely new formulations based on PPG’s own patented technologies. These antifoulings are based on self-release binder technology using Controlled Surface active Polymers (CSPs) which provide a self-lubrication and self-release mechanism to the coating.
PPG says that CSP acts on the coating/water interface as a lubricant, which supports laminar flow, thereby lowering the hull friction when the vessel is moving and delivering fuel savings averaging five per cent. In addition, CSPs create a ‘slippery surface’ that increases the resistance to fouling when the vessel is not sailing and, extending potential idle days.
Tom Molenda, PPG’s Global Marine Director, said: “The Sailadvance range has been developed in the knowledge that to meet today’s market needs, a coating must cover a wide range of vessel types and operational conditions. Owners want to reduce energy consumption and lower their total costs regardless of how their ships are operating.”
The Sailadvance range is designed for all vessel types and operating speeds and is particularly effective for slow-steaming because of the engineered CSP composition.
