INTRODUCTION
Zinc-rich paints have been used for many years in order to protect steel effectively in aggressive atmospheres, mainly in marine and industrial environments, against corrosion. The protection mechanism of this type of paint is based on the galvanic action of metallic zinc.|1~ Basic information about the evolution in formulations, characteristics, and applicability has already been made by Munger.|2~
The metallic zinc content in the dry film is a very important parameter to be emphasized in the technical specifications of zinc-rich paints. However, as observed by Lindquist et al.,|3~ this parameter is not the only factor determining the performance ...
