An anti-fouling film for marine organisms is a special film that has properties that make it difficult for marine organisms such as barnacles, crustaceans, mollusks, and algae (fouling organisms) to adhere in the ocean. By applying it to areas where marine fouling organisms are problematic, such as measuring instruments used in the ocean, marine sports equipment, fishing gear, boat bottoms, seawater intake areas, and structures where anti-fouling paint is difficult to apply, it becomes harder for fouling organisms to attach, and any minor adhesion can be easily wiped off, making maintenance easier. Additionally, since it has an adhesive film structure, you can choose between a strong adhesive type suitable for long-term use where peeling would be problematic, or a re-peelable type that can be applied and removed as needed, depending on the application.
