Abstract
The present invention relates to a corrosion inhibitor and inhibitor provided within a coating material for coating a metal, particularly but not exclusively steel. The corrosion inhibitor in a coating particularly protects a sacrificial coating such as zinc or zinc alloy on galvanised steel which in turn therefore provides improved corrosion resistance to the underlying steel. According to an aspect of the invention there is a corrosion inhibitor provided in a polymer binder, the corrosion inhibitor comprising an organic ion in an ion exchange resin.
