Abstract

The present invention has been made in an effort to provide an adhesive coating composition capable of adhering (fastening) a non-oriented electrical steel sheet without using a conventional fastening method such as welding, clamping, or interlocking, a non-oriented electrical steel sheet stack to which the same is applied, and a manufacturing method thereof. According to an exemplary embodiment of the present invention, an adhesive coating composition includes: 40 to 99 wt % of a first component containing a water-soluble resin; and 1 to 60 wt % of a second component containing a composite metal phosphate.
