Non-toxic anticorrosive pigments

Investigation of the anticorrosion efficiency of ferrites Mg1−xZnxFe2O4 with different particle morphology and chemical composition in epoxy-ester resin-based coatings

“…Their anticorrosion effect is based their reaction with a suitable binder which produces organometallic soaps [11]. Among their assets is their alkalinity, owing to which they are able to neutralise acid binders, thereby shifting the pH to a range which is less favourable for corrosion reactions [12]. Their environmental friendliness is also an important aspect.…”

Studies on corrosion resistant properties of inhibitive primed IPN coating systems in comparison with epoxy-PU systems

“…Today, among the inhibitive primers employed for corrosion protection, zinc phosphate primers enjoy a major share of applications in view of their less toxic nature. [16][17][18] Hence, to test the suitability of the developed IPN as a binder for such primer-based systems and to evaluate its performance, the following systems were designed and code named, as found in Table 1.…”

A new pigment for smart anticorrosive coatings

“…Many compounds have been suggested as possible replacements for chromates and lead compounds but zinc phosphate 1-10 and related substances became the leading substitutes for toxic inhibitors. [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] Other strategies have been developed to improve the performance of zinc phosphate. One of them consisted of the employment of more effective complementary pigments, such as zinc oxide or silicates, which reduced the level of the anticorrosive pigment content.…”
