Non-oriented Silicon Steel Insulating Coating Liquid is mainly applied to the non-oriented silicon steel sheet, which first used in the production of non-oriented electrical steel. At present, most of the domestics silicon steel producers adopted semi-organic masking liquid of Magnesium Chromate. The film formed by this coating material not only has the characteristics of good insulation, high heat resistance, but also possess strong adhesion, corrosion resistance, punching property and welkability.
* Coating Property
the coating without shedding during two hours under temperature 750℃
Salt Spray Test
with 5% NaCl solution, the corrosion area is less than 20%
