Influence of the pigment volume concentration (PVC) on the properties of an epoxy primer
Keywords:PVC, Epoxy, EIS, AC/DC/AC, Primer
By means of stress-strain tests, electrochemical techniques (EIS and AC/DC/AC) and salt spray accelerated tests, the influence of the A=PVC/CPVC parameter (being CPVC the critical pigment volume concentration) on mechanical and anticorrosive properties of an anticorrosive epoxy organic primer has been studied. 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).
