Copper Based Antifouling Coatings on Aluminium Hulls

E. Riding, Jotun Australia

Traditionally copper based antifouling coatings (mostly Cuprous Oxide) have not been used on aluminium hulls due the concern that corrosion of the hull will occur due to the electrochemical potential differences between the cuprous oxide and the aluminium hull. Recent laboratory investigation and a review of field experience has shown that there are other factors that are important to be properly controlled to avoid corrosion.
