FIELD: ferrous metallurgy.
SUBSTANCE: invention is related in particular to an insulating coating for electrical steel, which can be used for any known purpose. The proposed composition of the electrical insulating coating for electrical steel contains the following components, wt.%: AlPO4and Mg3(PO4)220-40, nanosized SiO2 2-15, K3O4V, VOHPO4, MnO (OH) 0.3-8, TiO20.01-2.5, water up to 100. The use of the specified composition as coating for electrical steel is also proposed.
EFFECT: obtaining a uniform electrical insulating coating with a matting effect, having a high coefficient of resistance of the insulating coating, high corrosion and moisture resistance, high adhesion of the coating to metal.
