NICHT AUF CHROMAT BASIERENDE KONVERSIONSBESCHICHTUNG FÜR METALLE |
| 摘要 |
Chromate-free treatments and compositions, for applying a conversion or passivation coating to zinc coated metal surfaces. The compositions comprise a polyamidoamine/epihalohydrin polymer or cationic polyamine/epihalohydrin polymer component, fluoacid, H<SUB>3</SUB>PO<SUB>4</SUB>, and a film forming polymer latex component. The requisite metal surfaces are contacted by the compositions and dried. Rinsing is optional. |
