Assessment of Marine Paints Based on Tubeworms and Sepia ShellWorld Applied Sciences Journal

Two Marine paints were prepared with the same formulation except one based on tubeworms (AF ) t and the second contains Sepia shell (AFs). The two paints together with their blank (B) were applied on unprimed steel panel and immersed in seawater. After 21 days of immersion the microbial examinations showed maximum inhibition of 43%, 25% and 64% for heterotrophic bacteria, actinomycetes and the sulfate reducing bacteria, respectively, on using Sepia shell based paint (AFs) surfaces compared to the blank coated steel surfaces. Also, the biological investigation showed after 70 days of immersion (AFS) surface was free from diatoms, primary stages of macroalgae and the polychaete larvae while primary stages of macroalgae were formed on the blank coated panels.
