| Title of Invention | A PROCESS FOR APPLYING A MULTILAYER PROTECTIVE COATING TO A SUBSTRATE AND A CORROSION RESISTANT ARTICLE |
|---|---|
| Abstract | The invention also relates to a process for applying a multilayer protective coating to a substrate having an electrically conductive surface, comprising: a fIrst method of forming a silicate layer upon said electrically conductive surface, said fIrst method comprising contacting at least a portion of said surface with a fIrst medium comprising at least one silicate and having a basic pH and wherein said first medium is substantially free of chromates, to form a silicate layer, and. a second method of electrolytically applying a synthetic resin layer upon the surface of said silicate layer, said second method comprising contacting at 'least a portion of said surface of said silicate layer with a second medium comprising a resinous ingredient, applying an electric current to said second medium wherein said surface is employed as an electrode, to form a synthetic resin layer, characterized in that said first method comprises introducing an electric current to said fIrst medium wherein said surface is employed as a cathode and said cathode comprises an article having zinc or zinc alloy surface. The invention also relates to a corrosion resistant article. |
