摘要： The present invention relates to a self-adhesive coating for electrical steel and its uses. The coating comprises 81-99.9 weight parts of aqueous epoxy resin emulsion, 0.07-17 weight parts of curing agent, and optionally 0.3 weight parts of accelerant. If required, said coating can optionally contain additives selected from diluent, filler, toughener, colorant, fire retardant, antirusting agent, antisettling agent, thixotropic agent or antifoamer, thickener, pigment dispersant, preservative, and the like. The coating can be used as electrical steel coating. The present coating is capable of making electrical steel with a self-adhesive coating in a way of heat by naked-flame, and also there are no poisonous organic solvents to volatilize during the entire process. Furthermore, the coating permits to omit apparatus for burning organic solvents, and the cost is thereby reduced.
