Weld Thru adhesion primer with high zinc content
The Weld Thru adhesion primer with high zinc content protects steel against rusting through sacrificial anodes or zinc plating. When applied to metal surfaces prior to MIG or spot welding, the zinc melts and bonds the surface to the steel, reducing the formation of rust and sub-surface rust.
