The research was carried out to utilize the aqueous solution and precipitation of hydrophosphate (containing Zn, Mn and Fe), which decreased the activity of film-formation. And it was found that the precipitation contaning phosphate is possible to be used again asrust preventitative by the addition of a hot solution of 2_??_3 percent of oxalic acid in finely powdered state. The film thus formed is applied as a basis for a coating of paint or other materials.
