Primers were formulated at different A values (0.73, 0.80, 0.88, 0.93, 0.98, 1.08, 1.15 and 1.24). It was concluded that mechanical and anticorrosive properties of an epoxy coating are greatly affected by the A parameter. The corrosion resistance increases when the PVC decreases. Anticorrosive properties characterized with the different techniques used were very similar, although AC/DC/AC offered the results in a very short time (24 h). ER -
