Since the worldwide ban of the use of tri-butyl-tin (TBT) in anti-fouling coatings in 2003, marine coatings manufacturers have been forced to reconstruct their paint formulations to accommodate different biocides, with copper designated as the favored candidate, supplemented by booster biocides. The palette of biocides available to paint manufacturers also faced new regulatory challenges in the shape of the EU Directive on Biocidal Products (98/8/EC). The impact of this Directive was a reduction in the number of certified biocides available for use in anti-fouling coatings to just 12 active substances. Shipping transportation is a globalized industry reliant on just-in-time delivery. Therefore, scheduling penalties, nor increased fuel costs are acceptable. An additional solution for barnacle fouling on ship hulls had to be found.
