Waterborne paints, an anticorrosive protection of steel surfaces, is an organic solvent-borne paints that helps protect steel surfaces exposed in atmospheres with different corrosivity categories. A prior knowledge of the atmospheric corrosivity including corrosivity category and corrosive agents present is essential for the correct specification of paint system. It is recommended to use paint systems with zinc-rich primers in atmospheres of great corrosivity such as marine atmospheres and damaged coating areas to assure good anticorrosive protection. Various tests were performed before and after atmospheric exposure to explain the behavior, adhesion characteristics, and water absorption rates, and it is observed that three waterborne paint systems including W4, W7, and W8 has the best overall anticorrosive behavior. These waterborne paint systems are the epoxy systems with zinc powder pigments in their respective primers and these systems present relatively low water absorption rates.
