SURFACE-TREATING AGENT COMPRISING CRYSTALLINE LAYERED INORGANIC COMPOUND DISPERSED IN NANOSHEET FORM.

摘要

Disclosed is a surface-treating agent comprising a crystalline layered inorganic compound formed with an organic amine or an organic ammonium into a nanosheet, wherein the organic amine or organic ammonium is a polyfucntional organic amine or polyfunctional organic ammonium. The surface-treating agent is a nanosheet-dispersed sol-type non-chromate surface-treating agent which shows excellent corrosion resistance and coating-adhesiveness at a processed part and can form a stiff film even used in the manufacture of a precoated metal plate which is applicable to an electric appliance, an automotive product or the like which is required to have a strictly machined shape.
