| Résumé : |
The corrosion of aluminum pigments in aqueous alkaline paint media, which results in the evolution of hydrogen, can be inhibited by certain substances. The combination of non-inhibiting paint resins with three corrosion inhibitors (salicylic acid, a fluorinated phosphate surfactant, and an epoxy ester resin) has been studied. The presence of the resins does not significantly affect the stabilization of the aluminum pigment at pH 10 by the corrosion inhibitors. With the addition of corrosion inhibitors, the hydrogen volume evolved from aqueous aluminum pigment dispersions is surprisingly reduced by stirring. However, when heated to +40°C aqueous aluminum pigment dispersions with inhibitors evolve more hydrogen ; at pH 8 the results are still satisfactory even at +40°C. |
