NON-CHROMATE CONVERSION COATING COMPOSITIONS, PROCESS FOR CONVERSION COATING METALS, AND ARTICLES SO COATED |
摘要 |
<p>In at least one aspect, the invention relates to an entirely or substantially chromium-free conversion coating composition and process for conversion coating metal surfaces that provides corrosion resistance. In at least another aspect, the present invention relates to an article having a metal surface that is at least partially coated with an entirely or substantially chromium-free conversion coating that provides corrosion resistance. In certain embodiments, the conversion coating composition comprises water and (A) dissolved fluorometallate anions selected from the group consisting of TiF6<-2>, ZrF6<-2>, HfF6<-2>, SiF6<-2>, AlF6<-3>, GeF6<-2>, SnF6<-2>, BF4<->, and mixtures thereof and (B) a water-soluble polymer which is a Mannich adduct of poly(4-vinyl phenol) and N-methyl ethanolamine. In other embodiments, the composition also comprises (C) a water-soluble polymer which is a Mannich adduct of poly(4-vinyl phenol) and N-methyl glucamine.</p> |
