Q:What can be painted on galvanized steel sheet?
Paint matching1. The paint preparation system used for galvanized steel in soaking or humid environment must be alkali resistant and can not be saponified. Therefore, it is advisable to choose epoxy type coating. Best with epoxy zinc yellow primer.2, for exposure in the dry environment of galvanized steel, zinc yellow epoxy primer can be used with acrylic polyurethane topcoat, or intermediate epoxy zinc chromate primer + epoxy micaceous iron oxide + fluorocarbon topcoat with ultra weatherability, long service life of the supporting scheme.In short, surface treatment is very important, considering the durability of galvanized parts, it is recommended to use the above two kinds of matching paint to ensure the normal service life and reduce the cost of intermediate maintenance.
