FIELD: metallurgy.
SUBSTANCE: invention refers to sheet of electro-technical steel with insulating coating and can be used in engines and transformers. The sheet out of electro-technical steel containing poly-siloxane polymer is produced by applying coating liquid on surface of sheet and in successive baking. Coating liquid contains 100 weight shares of poly-siloxane polymer preliminary prepared with co-polymerisation of poly-siloxane with one or more organic resins and from 1 to 50 weight shares in sum of one or more coupling agents. Organic resins are chosen from a group consisting of acrylic resin, sterol resin, vinyl-acetate resin, poly-ether resin, urethane resin, poly-ethylene resin, poly-propylene resin, phenol resin, alkyd resin and epoxy resin. The coupling agent is chosen from a group consisting of melamine, isocyanate, silane agent of combination and oxazoline.
EFFECT: production of sheet of electro-technical steel possessing upgraded corrosion resistance and ability to perforating.
