Abstract
A semi-organic insulation coating includes an inorganic component and an organic resin, a Zr compound and an Si compound contains a plate-like silica as an inorganic component and are included in a ratio in a dry coating of 20 to 70 mass % of Zr compound (converted to ZrO) and 10 to 50 mass % of Si compound containing plate-like silica (converted to SiO), and the remainder is substantially an organic resin, whereby a magnetic steel sheet with a semi-organic insulation coating has no deterioration of corrosion resistance and water resistance without containing a chromium compound and being excellent in powdering resistance, scratch resistance, sticking resistance, TIG weldability, punchability and coating appearance.
