Edge cover paint and method for forming thick coating film on edge of steel material by using the paint

摘要

This invention relates to a method for effectively forming thick coating film to improve the corrosion prevention of magnetic steel-materials edge, especially shrap edge generated by mechanical cutting. An edge cover paint which contains magnetic substance powder three to 40% of the weight in coating material solid content is used, when coating with the said paint or before paint solidifying (losing fluidity)after coating, the object to be coated such as steel is in the magnetic field, and thick film can be form in the edge using the magnetization characteristic difference of edge and adjacent plane.
