Coating Solution For Forming Insulating Film, Method For Forming Insulating Film Of Non Oriented Electrical Steel Sheet And Non Oriented Electrical Steel Sheet By Using It

Abstract: Disclosed is a coating composition having superior compatibility and surface gloss for forming an insulating film and a method of forming the film. The coating composition includes, based on 100 g of a mixture solution of monoaluminum phosphate and monozinc phosphate, 0.5-5 g of a mixture solution of cobalt hydroxide and strontium hydroxide, 150-300 g of a polyester emulsion resin, 3-10 g of aluminum silicate, and 0.5-6.0 g of a chelating agent, in which the polyester emulsion resin has a weight average molecular weight of 2,000-15,000, a solid content of 15-25% and a viscosity of 100-500 cp. Even when the coating composition which is chromium-free is applied in the form of a thick film on a non-oriented electrical steel sheet, superior ins...
