Abstract

The objective of this invention is to provide a waterborne epoxy coating that shortens the time from drying to curing. The waterborne epoxy coating of this invention comprises: a main agent containing a pigment, a solvent containing water, and a waterborne emulsion containing an epoxy resin; a curing agent containing a solvent containing water and a water-soluble organic solvent, and a polyamine having a plurality of amine groups; and a curing accelerator of 2,4,6-tris(dimethylaminomethyl)phenol; and a pH value of 10.1 or higher when the main agent, the curing agent, and the curing accelerator are mixed.
