PRETREATMENT COMPOSITIONS AND METHODS OF TREATING A SUBSTRATE |
| 摘要 |
Disclosed is a pretreatment composition containing (a) a Group IIIB metal, a Group IVB metal, or combinations thereof; and (b) a compound containing at least six phosphorus-containing acid groups or salts thereof; wherein the molar ratio of (a) to (b) is at least 3:1. Also disclosed are methods of treating a substrate with the pretreatment composition and substrates treated with the pretreatment composition. |

1. A pretreatment composition comprising:
(a) a Group IIIB metal and/or a Group IVB metal present in a total amount of 20 ppm to 1000 ppm (calculated as elemental metal) based on the total weight of the pretreatment composition; and (b) a compound containing at least six phosphorus-containing acid groups or salts thereof present in an amount of 1.82×10−4 moles per liter to 2.73×10−2 moles per liter of pretreatment composition; wherein the molar ratio of (a) to (b) is at least 3:1. |
