Strategies to combat biological growth in marine coatings

Tuesday, 10 January 2012

Oxygen depleted surfaces, enzymes degrading barnacle glues, and anti-barnacle biocides will be discussed at the European Coatings Conference "Marine coatings” in February.

Three strategies to combat biological growth on boat hulls will be discussed in a presentation at the European Coatings Conference "Marine coatings” on 28 and 29 February, 2012 in Berlin: oxygen depleted surfaces, enzymes degrading barnacle glues, and anti-barnacle biocide. The first one is based on that bacteria growing on a surface consume oxygen. If the growth is fast enough oxygen will be depleted from the boat hull surface making life conditions for algae, barnacle and so on very uncomfortable. The second one is based on that certain enzymes can degrade barnacle glues so that the barnacle cannot stay attached to the boat surface. The third one is based on a biocide with a very low solubility in water. As such it is expected to stay in the coating and that barnacles when attaching to the surface will be exposed to the biocide and then will fall off from the coating surface.
