A multipurpose compound dor protective coatings

International regulations concerning the protection of both the environment and industrial workers have prompted paint manufacturers and end users to look for suitable replacements for traditional pigments. One of the aims of this investigation was to study the inhibitive properties of ferric benzoa...

One of the aims of this investigation was to study the inhibitive properties of ferric benzoate-based paints in simulated marine corrosion condition (3% NaCl solution).
