| Description |
Wash primer treatment of galvanized iron (GI) structure is widely used before painting in order to improve
adhesion. Traditional wash primer contains zinc tetroxy chromate. Due to hazardous nature of chromate,
alternate compounds for chromate replacements have been identified. In recent years polyaniline containing
coating has been found to protect GI. In this study, a wash primer based on polyaniline has been
formulated and its corrosion protection ability of GI has been compared with that of traditional chromate
based wash primer by salt spray and EIS test. It has been found that the polyaniline based wash primer
is able to protect GI and its corrosion protection performance is similar to chromate based wash primer
coating.
