Resumen:
Anticorrosive properties two commercially available phosphate pigments, wich differents molybdenum content in their composition, have been investigated. The anticorrosive properties of the pigments were assessed by electrochemical techniques in pigments suspensions and then in solvent and water-borne paints. The paints contained 30% by volume of anticorrosive pigment, with respect to the total pigment content.
The anticorrosive performance of paints formulated with different binders (alkyd, epoxy and water-borne epoxy) has been evaluated by accelerated (salt sapray cabinet and humidity chamber) and electrochemical (corrosion potential and ionic resistance) tests.
It was found that paints formulated with both pigments behaved satisfactorily in accelerated tests and both provided very good anticorrosive protection to steel. the pigment with the highest molybdenum content showed a better performance in water-borne paints.
