Chugoku Marine Paints expands Selektope®-containing antifouling coating range

08 July 2019 – 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. Developed initially for use in the Japanese domestic market by coastal vessels, SEA PREMIER 3000 PLUS is particularly suitable for vessels operating with a low activity rate or at low speed. The coating is also suitable for use in niche areas, such as sea chests and interior-grating-bow thruster tunnels.

“The increasing range of Selektope®-containing products introduced to the market by our largest customer further demonstrates our technology’s vital contribution to enhancing the performance and differentiation of antifouling coatings. Expanding the range of Selektope®-containing products in the world’s third largest market* for marine coatings will contribute to continued long-term growth for I-Tech,” says Philip Chaabane, CEO, I-Tech AB (PUBL).

About I-Tech AB

I-Tech is a biotechnology company that has developed the product Selektope®, an active agent that prevents barnacle attachment on submerged surfaces such as ships and boat hulls, but also other marine installations. By increasing the resistance to barnacle growth in marine paint systems (e.g. antifouling coatings), fuel and maintenance costs are reduced. I-Tech has obtained the necessary regulatory approvals for Selektope® and has several of the world’s largest manufacturers of marine antifouling coatings as customers. The company’s share is listed for trading on Nasdaq First North in Stockholm with Erik Penser Bank as Certified Adviser, phone: +46 (0)8 463 83 00, email:


About Selektope®

Selektope® is an organic, non-metal compound that prevents barnacle fouling with a non-fatal effect on the target organism. When added to antifouling coatings, Selektope® prevents the settlement of barnacles on a ship’s hull by temporarily activating the barnacle larvae’s swimming behavior by selective receptor stimulation.  Selektope® is characterized by high efficacy at extremely low recommended concentrations of 0.1% w/w.



Superior antifouling performance with silyl polymer technology and stable surface renewal for Japanese domestic coastal vessels. Provides excellent antifouling performance for ships with a high risk of fouling depending on the route and operating conditions. SEA PREMIER 3000 PLUS enables linear and consistent polishing throughout the life of the system. The leach layer is optimally controlled to further improve the surface renewability and maintain excellent antifouling performance.
The ultra-smooth coated surface of the SEA PREMIER 3000 PLUS reduces the ship’s frictional resistance and achieves a fuel consumption reduction of 5 to 8%* compared to conventional hydrolyzable bottom antifouling paints.
