Anti-fouling Agents
Anti-fouling agents are substances or coatings applied to the hulls of ships to prevent the accumulation of marine organisms such as barnacles, algae, and mollusks. These organisms can attach themselves to the hull and increase drag, reducing the ship's speed and fuel efficiency. Anti-fouling agents work by either preventing the attachment of organisms or by releasing toxic substances that deter their growth. Copper-based compounds are commonly used as anti-fouling agents, but there are concerns about their environmental impact. Other alternatives such as silicone-based coatings and non-toxic biocides are being developed and tested.
