Building on its Hempasil range of fouling-release systems, marine coatings manufacturer Hempel has announced the launch of a new antifouling solution "to deliver optimal fuel savings and return on investment".

The new Hempasil X3+ is a biocide-free, two-component, fouling-release coating with a high solids content that is said to ensure clean hulls for longer periods.

In a statement, Denmark-headquartered Hempel said: "Hempasil X3+ creates a smooth, low energy surface with unique fouling-release properties. Its hydrogel micro layer prevents fouling organisms from firmly adhering to the hull while retaining the self-cleaning properties of silicone. The product is a completely biocide-free paint and has no impact on the marine environment which assists shipowners fulfil their obligations to the environment."

This latest solution from Hempel is based on hydrogel technology comprising a network of advanced polymer chains which absorb high amounts of water (to a level of more than 99%) to create a water-like boundary layer. This layer effectively tricks the fouling organisms into believing the hull is a liquid and not a solid surface and this minimises protein and bacterial adhesion.

Commenting on the launch, Henrik Dyrholm, Hempel's Group Product Manager, said: "This innovative new coating has been developed in consultation with our customers to offer an additional choice for owners and yards and to deliver optimal fuel savings. Due to its high efficiency, the Hempasil X3+ will significantly reduce the carbon footprint of a vessel making it the ideal choice for environmentally aware shipowners, who want the best for the environment and their business. Our innovative hydrogel technology gives an additional layer of protection that remains present and stable over time to provide optimal fouling prevention and performance."
