In addition to the protection of zinc layer, the organic coating on the zinc layer plays a role in covering and protecting the color coated steel strip with hot-dip galvanized steel strip as the base material, preventing the steel strip from rusting, and the service life is about 1.5 times longer than that of the galvanized steel strip.
V coating structure type
2 / 1: twice for upper surface, once for lower surface and twice for baking.
2 / 1m: coating the upper and lower surfaces twice, baking once.
2 / 2: coating the upper and lower surfaces twice, baking twice.
V Application of different coating structures:
2 / 1: the single-layer back paint has poor corrosion resistance and scratch resistance, but has good adhesion, which is mainly used in sandwich panel;
2 / 1m: the back paint has good corrosion resistance, scratch resistance and processing formability, and has good adhesion. It is suitable for single-layer profiled board and sandwich board.
2 / 2: the double-layer back paint has good corrosion resistance, scratch resistance and processing formability, most of which are used for single-layer profiled plate, but its poor adhesion is not suitable for sandwich plate.
