| abstract | COATING COMPOSITIONS AND METHOD FOR THE TREATMENT OF METAL SURFACES ABSTRACT An aqeuous acidic composition provides improved coating for aluminum. The composition comprises from about 10 to about 150 ppm zirconium, from about 20 to about 250 ppm fluoride, from about 30 to about 125 ppm tannin, from about 15 to about 100 ppm phosphate and from about 5 to about 50 ppm zinc, said coating solution having a tannin to phosphate ratio in the range of at least about 1:1 to about 2:1 and a pH in the range of about 2.3 to about 2.95. |
