Improved chromium-free composition and process for corrosion resisting treatments for aluminum surfaces |
| abstract |
An exceptionally effective chromium free corrosion protective surface treatment composition for aluminum and its alloys is an aqueous acidic liquid comprising water and: (A) from about 0.8 to about 1.2 w/o of H2?ZrF6?; (B) from about 0.08 to about 0.12 w/o of dispersed silica; (C) from about 0.08 to about 0.12 w/o of a water soluble or dispersible polymer of 3-(N-methyl-N-2-hydroxyethyl-aminomethyl)-4-hydroxystyrene; and (D) from 0.10 - 0.15 w/o of 1-propoxy-2-propanol. The surface to be treated is contacted with the composition and then dried without rinsing. A conventional organic coating may advantageously be applied over the surface produced by this treatment. |
