    摘要: Composition for sealing phosphatized metal components to improve corrosion resistance and paint adhesion, which consists essentially of:

    (a) from 5 to 80 weight percent phosphoric acid;
    (b) from 1 to 16 weight percent of an acidsoluble zinc compound;
    (c) from 0.1 to 10 weight percent of a heavy metal accelerator and/or crystal refiner;
    (d) from 1 to 80 weight percent of a phosphonate corrosion inhibitor; and
    (e) sufficient water to dilute the composition to its desired strength.
