Potential of a marine bacterium extract

Scientists have studied the antifouling and anticorrosion potential of Pseudoalteromonas piscicida 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).

EC Library The Rheology Handbook


The Rheology Handbook

Already in its 5th edition, this standard work describes the principles of rheology clearly, vividly and in practical terms. The book includes the rheology of additives in waterborne dispersions and surfactant systems. Not only it is a great reference book, it can also serve as a textbook for studying the theory behind the methods. The practical use of rheology is presented in the areas quality control, production and application, chemical and mechanical engineering, materials science and industrial research and development. After reading this book, the reader should be able to perform tests with rotational and oscillatory rheometers and interpret the results correctly.
