Potential of a marine bacterium extract
The aim of the study was to estimate antifouling and anticorrosion potential of organic extracts from Pseudoalteromonas piscicida 2202.
Field tests of rosin-based experimental paint indicate that butanol extract of P. piscicida 2202 effectively prevents biofouling for 3 months. A protective film forms at the metal/solution interface in the presence of butanol extract, which leads to a decrease in the mild steel corrosion rate.
Improved the barrier properties
The EIS method has shown that the incorporation of butanol extract in rosin-based paints improves the barrier properties of the coating by reducing the water uptake.
The study has been published in Journal of Coatings Technology and Research volume 17 (2020).
