Aluminum treatment with alkaline solution and tannin |
| abstract |
A chromium-free treatment for aluminum imparts corrosion resistance and paint receptivity to the surface. The process is sequential and includes a first contact with an aqueous alkaline solution (pH above 10) containing complexed iron ion, water rinsing, and then contact with an aqueous acidic organic tannin-containing composition. |
