M. Selvaraj et S. Guruviah, THE ELECTROCHEMICAL ASPECTS OF THE INFLUENCE OF DIFFERENT BINDERS ON THE CORROSION PROTECTION AFFORDED BY ZINC-RICH PAINTS, Surface coatings international, 80(1), 1997, pp. 12
The corrosion protection characteristic of butyl titanate, epoxy polya
mide and Cashew Nut Shell Liquid-based zinc-rich paints has been studi
ed by taking measurements at different temperatures and time intervals
of galvanic current, potential and impedance at 3% sodium chloride so
lution. The independent cathodic and barrier mechanisms of corrosion p
rotection afforded by these paints has been distinguished. The scannin
g electron microscope studies also support the protective action of th
e butyl titanate-based zinc-rich paint that arises from thw wetting of
the zinc particles by this binder.
