HULLMAINTENANCE combat marine growth. Sherwin-Williams marketing executives say that a key component of SeaGuard is that the anti-fouling agent in SeaGuard does not persist in the marine environment and it has an extremely short hydrolytic halflife—it breaks down in less than 24 hours. SeaGuard is part of Sherwin-Williams’ EcoVision initiative, a company-wide commitment to reducing its impact on the environment. In addition, Sherwin-Williams executives point out that because SeaGuard does not contain copper like traditional anti-foulings there is substantial weight savings—as much as 5 pounds per gallon or 40% less weight. This, in turn, translates into added fuel savings. “SeaGuard Heavy Metal Free Antifoulant is a first in our product offering to the U.S. military and U.S. commercial ship owners—an environmentally responsible alternative to metal-based anti-foulings that not only meets performance expectations but can actually increase fuel efficiency or allow for added cargo, both of which add to the bottom line,” said Doni Riddle, Vice President, Sherwin-Williams Protective & Marine Coatings Division. SeaGuard Heavy Metal Free Antifoulant is an ablative coating, which allows the coating surface to slough off gradually, exposing new biocide that maintains the coating’s effectiveness over time. It can be used to overcoat existing anti-fouling coating systems. SherwinWilliams says SeaGuard has been approved by the Navy for a three-year service life. FILLING THE GAP Back in 2000, Jotun A/S, which has its head office in Sandefjord, Norway, launched SeaQuantum, its first TBT-free, self-smoothing and self-polishing anti-fouling. Later, SeaQuantum was joined by another TBTfree anti-fouling, SeaForce. This past November, Jotun added SeaMate—a new self-smoothing and self-polishing hydrolysis anti-fouling based on silyl acrylate technology. SeaMate is a hydrolyzing silyl acrylate antifouling. Its self-smoothing and self-polishing effect enables vessels sailing between 12-26 knots to significantly reduce fuel consumption and carbon emissions over time. According to Geir Boe, Divisional Vice President for Jotun Marine Coatings, SeaMate fills an important gap in the company’s well known brands SeaForce and SeaQuantum. Boe says SeaMate is a more affordable alternative. “We are confident SeaMate will meet the market demand, especially in the tanker and bulker segments.” The unique properties of SeaMate based on silyl acrylate technology gives excellent technical qualities, enabling rapid drying and reducing both application and materials costs. SeaMate also gives a hard finish offering protection against mechanical damage. All anti-foulings release biocides resulting in the formation of a leached layer. However, by maintaining a low leached layer and a linear polishing pattern for the full 60 months period SeaMate delivers a constant release of the biocides.
