Preventing of material loss due to corrosion and fouling of steel surfaces is a serious challenge for oil and gas industries. The use of protective polymeric coatings containing active biocides is an interesting approach to address this problem. The development of active anticorrosion/antifouling coatings via this approach requires the careful design and optimization of the coating matrix selecting the proper biocide and ultimately achieving the synergy between the two components. In this study a novel hybrid epoxy-siliconized coating was synthesized through a sol-gel technique and subsequently doped with different organic and inorganic antibacterial agents. The undoped and doped-coatings were applied on mild steel sheets and their corrosion protection performances in lab were evaluated using Electrochemical Impedance Spectroscopy (EIS) and DC polarization techniques and visual observations. The field testing of the anticorrosion and antifouling properties of all coatings was conducted also by immersing the coated panels under the sea water at a marine exposure site. Electrochemical lab analyses and field testing revealed good barrier and corrosion protection properties for the coated panels in comparison with untreated mild steel coated panel following long term immersion in saline medium. Moreover field testing results indicated a lack of synergy between some antibacterial agents and the newly-developed hybrid coating while the addition of other agents were found to have a positive impact on the anticorrosion and antifouling behaviour of the hybrid coating.

Key words: Sol-gel, biocide, corrosion, coatings, mild steel, fouling.

This paper will consider the performance and relevance to static situations of the key types of Cathodic dip painting (CDP) Antifoulings (Rosin Modified types), the current tin free polishing types (typically acrylates of various types), and low energy surface types. Both field experience and laboratory work will be considered.
