• Promising results after one summer

• Not the long lasting protection the sector is looking for

• Once the AF layer will be depleted the TSA will be attacked by fouling and corrode more rapidly

• Good preliminary results and potentially very long lasting corrosion protection, ca10µm/year

• In order to eliminate completely the barnacles a new generation of coating has been prepared with more polymer inside

3rd Generation Oceanic Coating : Demonstration (Shackle/eyebolt) – Deba, Basque Countries

From 1st of september 2018 Until 22nd of november 2018

Production laboratory and field test and selection of anticorrosion alloys

Compounding, Cryogrinding and selection of polymer containing active ingredient for antifouling

Process and equipment for “All In One” Anticorrosion/Antibarnacle coating process developed

Compiling and dissemination of free to consult fouling database: www.oceanic-project.eu/biofouling-database
