| Abstract: | The microbial
attack on coatings used in aircraft fuel tanks has important implications
because such coatings or sealants must remain intact for effective corrosion
protection. In general, all the polysulphide based sealants under test were found
to be very effective against individual cultures, viz. sulphate reducing bacteria (SRB) and Aureobasidium pullulans. However, when the cultures were introduced
collectively (viz. mixed and combination), growth of microorganisms resulted in
degradation of coatings to a greater extent. Analysis of electrochemical data
reveals that sealant RDL-854 can be used as a broad-spectrum sealant as it was
found effective not only against single cultures but also when cultures were
introduced collectively. |
