Zinc basic benzoate as eco-friendly steel corrosion inhibitor pigment for anticorrosive epoxy-coatings

The inhibitive properties of benzoate anion were known from many years ago but the employment of soluble compounds in anticorrosive paints is limited because their lixiviation would greatly increase coating permeability. However, it is possible to prepare insoluble metallic benzoates with certain ca...
