Thordon Bearings reports it has secured a second major Mexican Navy contract for the supply of its water-lubricated SXL wear rings for retrofit installation to the waterjet propulsion nozzles on 25 interceptor patrol vessels.The contract follows the success of extensive trials in which the SXL material replaced the use of other anti-corrosive coatings in waterjet impeller housings, resulting in increased resistance to cavitation induced corrosion.Rotary Parts, Thordon’s authorized distributor in Mexico, is supplying the housings for 25 Polaris and Polaris II fast patrol boats.

Thordon Bearings’ founder and polymer materials pioneer George A. (Sandy) Thomson has been awarded the global transportation sector’s most distinguished accolade, the Elmer A. Sperry Award 2019 for “Advancing the Art of Transportation”.Thomson joins a long list of Sperry Award recipients, which was established in 1955, including Donald Douglas, Ferdinand Porsche, Sir Geoffrey De Havilland, Christopher Cockerell, Leonard Hobbs, Perry Pratt, Josef Becker and Malcom McLean.“I am deeply honored and humbled to win this award…

A new antifouling coating containing the barnacle-repellent active agent Selektope has been introduced to the market by Chugoku Marine Paints (CMP). SEA PREMIER 3000 PLUS is the eighth product developed by CMP that contains Selektope, demonstrating the Japanese paint manufacturer’s growing commitment to the technology.SEA PREMIER 3000 PLUS is a self-polishing coating based on silyl polymer technology. It delivers excellent slime and algal resistance with the combined power of Selektope and cuprous oxide for superior hard fouling prevention.

AkzoNobel said it scooped two honors at the recent ICIS Innovation Awards for the Interline 9001 ultra-performance cargo tank coating supplied through its International brand. As well as being awarded with the overall Innovation Award, Interline 9001 also received the Best Product Innovation Award from ICIS, the trusted information provider for the global chemical and energy industries. The awards recognize the impact the new coating has had on the chemical tanker industry, specifically how it tackles the issue of absorption from aggressive cargoes…

The first branded marine coatings to feature the antifouling ingredient Selektope have been launched by coatings major Chugoku Marine Paints, Ltd. (CMP). Developed by I-TECH AB, Selektope’s pharmacological action is unique in the marine antifouling application. It repels barnacle settlement on ships’ hulls by temporarily stimulating the barnacle larvae’s swimming behavior. CMP’s new generation ‘SEAFLO NEO’ range of antifoulings make the Selektope solution available as a high performance product for mainstream operations…

PPG caps a busy 2013 by launching three separate coatings; each intended for a specific application. As regulatory and operational requirements drive coatings decisions, it’s increasingly clear that, on the water, one size does not fit all anymore. You can get there, nevertheless, by the numbers. It has been a busy year for PPG Protective and Marine Coatings (PPG). With at least three new marine product releases and even a new production plant in Poland, the Pittsburgh, PA-based global coatings and specialty products company hasn’t stopped long enough to give the proverbial barnacles the smallest chance to slow its growth. Founded in 1883 and operating in nearly 70 countries around the world, PPG’s sales in 2012 exceeded $15 billion.

PPG Industries introduce Sigma Syladvance 700 coating to protect vessels with flexible service speeds, trade patterns. Based on the successful Sigma Syladvance 800 premium antifouling product, PPG say that their new Sigma Syladvance 700 coating extends the line with an "entry-level" product, making premium technology available for a different set of requirements. Sijmen Visser, PPG global marketing manager, marine, said, “Antifouling coatings have evolved over the past decade…

PPG Protective and Marine Coatings (PPG) has launched Sigma Syladvance 700, a high performance antifouling designed specifically for ships working at medium to high rates of operation and  medium speeds. Based on the Sigma Syladvance 800 premium antifouling product, Sigma Syladvance 700 extends the product offer by means of an “entry-level” Sigma Syladvance making premium technology available for a different set of requirements. Sigma Syladvance 700 is based on patented silyl acrylate polymer technology and offers self-smoothing properties and outstanding fouling protection.

The advance of modern marine coatings and related technologies is not unlike other technical sectors of the maritime industry, primarily driven by emerging regulation from the international, national and regional level, usually in regard to environmental concern. But in recent years, an increased focus on the reduction of marine emissions in tandem with the capability to more directly correlate clean, well-maintained hulls with reduced fuel consumption and lower emissions has driven the industry further faster…

International Paint introduce Intercept®8000 LPP & Intersleek®1100SR a biocide-free slime release coating. Designed to address the industry issues of predictability in antifouling performance not seen since the days of tributyltin and the difficult issue of slime fouling on ships hulls, the two new technologies are set to improve vessel operating performance, increase efficiency and help control fuel costs and emissions. • Intersleek®1100SR, is the industry’s first biocide free fouling control coating featuring unique patented slime release technology that combats micro fouling on ships hulls, maintaining performance throughout the docking cycle . The unique LUBYON® polymer technology gives the coating a ‘superhydrophilic’ surface.

Lonza is pleased to announce it has received a registration from the U.S. EPA for the use of its copper Omadine Antimicrobial as an agent to deter the growth of algae and other foulants on ships. The registration covers the product’s use in marine hull paints that are applied by licensed applicators on U.S. vessels that are 25 or more meters in length. “This registration means our customers can now provide their latest antifouling paint technology in the United States,” explains Robert Martin, Global Strategic Marketing Manager for Lonza Microbial Control’s Marine Antifouling Paint business. “Many of the new self-polishing paints contain copper Omadine® Antimicrobial, the most widely used co-biocide in the world for marine antifouling paint applications.

Approximately 700 shareholders attended Trelleborg’s recent Annual General Meeting in Trelleborg . The theme of CEO Peter Nilsson’s address was “A continuously evolving Trelleborg”. “2011 was the best year so far for Trelleborg. We achieved our financial goals and strengthened our finances. We continued our determined efforts to achieve sustainable profitable growth by gradually strengthening and developing the Group. “Our ambitious activities to develop the Group have yielded results.

International Paint introduced Intersmooth 7465Si SPC and Interswift 6900Si silyl acrylate antifouling coatings. The company reports that it is first to offer both copper acrylate and silyl acrylate antifouling coatings within a comprehensive range of fouling control technologies. In 2006, International Paint patented silyl acrylate technology for use with products of <400g/l VOC (volatile organic compounds). This technology is incorporated into Intersmooth 7465Si SPC and Interswift 6900Si and allows delivery of the same performance as its current Intersmooth 7460/5HS SPC and Interswift 6800HS copper acrylate antifouling coatings. Both new silyl products have solvent emission levels of less than 400g/l VOC.
