Chrome-free methods of etching organic polymers with mixed acid solutions |
| abstract |
A chromium-acidic aqueous solution of sulfuric acid and at least one organic acid and manganese (II) and (III) ions is applied to the organic polymer surface for surface etching. The etched surface is then plated with metal. |
