Composition and method for forming insulating films on electrical steel

A method of manufacturing a vinyl chloride-coated steel sheet involving the steps of coating electron ray curable adhesives on the surface of the thin metal sheet, such as a zinc plated steel sheet or cold rolled steel sheet, laminating a vinyl choride film of decorative and corrosion resistant protecting property to the coated surface and irradiating electron rays the upper surface of the coated sheet with thereby bonding the film with the metal sheet as raw material, wherein the vinyl chloride film is formed by applying a calendering or extruding process to a blend including a vinyl chloride resin obtained by suspension polymerization and, from 20 to 40 parts by weight of a plasticizer, dialkyl tin mercaptide type stabilizer, an acryl oligomer type lubricant and, optionally, pigments and other ingredients. Combined use of the dialyl in mercaptide stabilizer and the acryl oligomer lubricant has been found to be particularly suitable for electron ray irradiation, as well as to the subsequent UV-ray exposure which would otherwise cause significant degradation in the vinyl chloride coating.
