Process and composition for passivating metal surfaces |
| abstract |
Aqueous compositions useful as a passivation treatment prior to painting to reduce corrosion. The compositions includes water, a trivalent chromium salt with the formula Cr(HxPO4)3, where x is 1.5 or 2, a polymer system having a plurality of carboxylic functional groups, an organo-functional silane, and an organopolyphosphonic acid. A process for treating a metal surface includes contacting the surface with such aqueous compositions. The compositions and the processes provide benefits in comparison to the zinc phosphate metal pretreatment thought to be the standard in the industry. |
