Title: Method for applying an organic coating onto an inorganic coated steel sheet

Abstract: A method is provided for improving the insulating characteristics of oriented steel sheet having an inorganic surface coating to produce an organic resin-in-organic coating-oriented steel sheet composite. Certain irradiation curable solventless organic resins can be applied to the surface of the oriented steel sheet in a pollution free manner. The resulting composite can be used as power transformer core laminate.
