Calcium tannate was synthesized, characterized, and dispersed into an epoxy coating as inhibitive pigment. Electrochemical Impedance Spectroscopy (EIS) employed to monitor the anti-corrosive performance of formulated with as-prepared pigment after exposure salt spray chamber. Reference coatings commercial calcium phosphate unpigmented were also evaluated for comparison reasons. EIS results show...

Water at the interface is often the main cause of corro. sion, blistering, and disbandment of organic coating/substrate systems. Consequently, the transport of water from the environment to the coating/substrate interface is the subject of great interest in many industries such as organic coatings, asphalt pavements, and electronic packaging. There is no suitable method available to measure the...
