Discover Hempel’s latest innovation and technological achievement - Silic One! Available in shades: Red Black Blue Silic One Biocide free product based on silicone and hydrogel, which gives the coating surface waterlike properties making it difficult for fouling organisms to attach to the hull and easy for them to be removed when the boat is in motion. hydrogel are evenly distributed in the paint film. If the original hydrogel is removed, a new hydrogel layer instantly builds up when the polymer, responsible for hydrogel formation, comes into contact with water. What is Fouling Release...

Antifouling vs. Fouling Release Which fouling control method is right for you? Silicone Fouling Release Antifouling works by releasing biocides, in a controlled manner, to prevent fouling organisms from attaching to the boat. Upon exposure to water the top layer of antifouling is dissolved, and the biocides “leach” onto the coating surface, therefore keeping fouling organisms away. Unlike antifouling, the Fouling Release System doesn’t rely on biocides. This product is based on silicone and hydrogel, which gives the coating surface waterlike properties, making it difficult for fouling...
