SHEET OF ELECTRICAL STEEL WITH INSULATING COATING AND METHOD FOR ITS PRODUCTION Russian patent published in 2010 - IPC C23C26/00 C21D9/46 B05D7/24 B32B15/08 

Abstract RU 2400563 C2

FIELD: metallurgy.

SUBSTANCE: sheet has insulating coating containing composite resin consisting of polysiloxane and polymer containing carbon element. Method involves application of composite resin and burning at temperature of 150 to 350°C till the coating with weight of 0.05 g/m2 to 10 g/m2 is formed.

EFFECT: obtaining the sheet with insulating coating providing high corrosion resistance and formability, which are equivalent to or higher than those properties of chrome-containing insulating coating.
