N2 - The physicochemical features of a surfactant are quite important in the formulation of polymer water-borne coatings mainly due to the strong influence of the micelles on the nucleation and stability of dispersed polymer particles. In consequence, micellar transitions must be determined in order to obtain aqueous dispersions of spherical shaped particles with high monodispersion in size, which allows to obtain coatings with an improved performance. Besides, depending on its chemical structure, the surfactant could also have anticorrosive properties. In this work, a phosphate-based surfactant was characterised and its electrochemical properties were evaluated in order to use it as a stabiliser agent of a series of monodisperse styrene-acrylic lattices, synthesised by semi-continuous emulsion polymerisation. EIS was used to evaluate the anticorrosive properties of coatings obtained from polymeric dispersions.
