Learn what sets F2 apart from traditional antifouling. Discover how this eco-friendly hybrid-polymer coating protects your boat—without the use of harmful biocides.

F2 is an eco-friendly hybrid-polymer coating that effectively protects your boat from underwater fouling. Unlike traditional antifouling, F2 does not rely on biocides, toxins, or other harmful substances. Instead, it forms an extremely smooth, water-repellent surface that simply repels marine growth.Here are the key differences:<ul><li>Mode of Action: Traditional antifouling continuously releases biocides into the water to kill organisms. In contrast, F2 physically prevents fouling from settling in the first place.</li><li>Eco-Friendliness: F2 is 100% free of harmful substances such as biocides, silicones, PFAS/PTFE, and VOCs (volatile organic compounds).</li><li>Durability: While traditional antifouling wears down over time and typically requires yearly renewal, F2 is extremely durable and, with proper application and care, lasts for at least 5 years.</li></ul>Good to know: The effectiveness of F2 Eco has been confirmed in independent tests. See the test results from Endures B.V. <a href="https://f2eco.eu/blogs/news/endures-report" target="_blank" rel="noopener noreferrer">here</a>.

What is F2 and how does it differ from traditional antifouling?

Learn the fundamental difference between antifouling and fouling-release systems. We explain the mechanism of action and why F2 is the more eco-friendly solution.

The main difference lies in the mechanism of action. Both systems protect against fouling, but they do so in fundamentally different ways.<hr>Traditional AntifoulingThese products prevent fouling by continuously releasing biocides (chemical toxins) into the water. These substances kill microorganisms before they can attach to the surface. As the layer wears away in this process, the antifouling usually needs to be sanded and renewed annually.Fouling-Release SystemsFouling-release systems work purely physically. They create an extremely smooth, water-repellent surface that makes it difficult for organisms to gain a foothold at all. Any deposits that do settle adhere only very weakly. They either release on their own during normal cruising or can be removed by simple, gentle cleaning.<hr>Important: Biocide-free doesn&apos;t automatically mean eco-friendlyCalling a product &quot;biocide-free&quot; is a good start, but it&apos;s not enough. Abrasion, solvents, and PFAS (per- and polyfluoroalkyl substances) can also harm the environment.F2 Eco meets the highest environmental standards: It is biocide-, PFAS-, and solvent-free. Since it also doesn&apos;t wear away or leach, no particles or pollutants enter the water. It&apos;s a true fouling-release system designed for a lifespan of at least five years.

Antifouling vs. Fouling-Release: What is the difference?

The test proves that F2 makes maintenance predictable and allows you to benefit from its effectiveness as a long-term system with at least five years of durability (with correct application and care).You can find more details and images from the test in our blog: <a data-fr-linked="true" href="https://f2eco.eu/de/blogs/news/endures-report" id="isPasted">https://f2eco.eu/blogs/news/endures-report</a>.

Are there independent tests that prove the effectiveness of F2 Eco?

Learn how F2 handles fouling. The smooth F2 surface reduces adhesion and simplifies cleaning – for a sustainably clean underwater hull.

No, no system can guarantee a 100% fouling-free surface. However, F2 offers an extremely effective and durable protection that reduces fouling adhesion to a minimum and significantly simplifies maintenance.What You Can Expect:<ul><li>Barely any hard fouling: Hard fouling like barnacles, coral worms, or mussels will barely adhere with F2, as the extremely smooth and water-repellent surface makes solid attachment nearly impossible.</li><li>Cleaning without great effort: Surface fouling, especially bioslime, can be easily wiped away with a cloth or soft sponge. Tedious scraping or annual repainting is no longer necessary.</li><li>Protection against structural damage: The F2 surface cannot be penetrated by organisms like barnacles or coral worms. The coating remains intact, even if the boat is not cleaned for a long time.</li><li>Natural self-cleaning effect: Part of the light fouling is removed even during normal cruising. This effect is further enhanced at speeds of around 10 knots and above &#x2013; depending on the hull shape, cruising time, and local conditions.</li></ul>The effectiveness of F2 was also confirmed in the independent test report by the Endures B.V. Institute. It was proven that F2 reduces hard fouling to a minimum and that light deposits can be easily removed with gentle cleaning.

Find out why the F2 coating won't peel, become brittle, or flake off. The durable, abrasion-resistant layer provides long-term protection for your boat.

No. When F2 is correctly applied to a prepared surface, it won&apos;t become brittle, flake, or peel off. F2 was developed as a long-lasting, hard coating system that bonds firmly to the hull. Unlike traditional antifouling that dissolves over time, F2 remains intact, forming an extremely durable, abrasion-resistant protective layer. Peeling only occurs if the surface was not properly prepared or if moisture is trapped.

Does F2 get brittle, flake, or peel off?

Can a boat with F2 be stored on land? Yes. Learn why F2 is UV-resistant and why the coating doesn't need to be renewed after long periods of dry storage.

The F2 coating is extremely resilient and highly UV-resistant. This means that the coating will not become brittle or flake off when your boat is on land for an extended period. On the contrary, the protective layer remains intact and fully functional.Since F2 does not dry out, you don&apos;t need to renew the coating before putting your boat back in the water. You can simply clean it and launch it directly.

How does F2 behave when the boat is on land?
