  • Zinc phosphate tungsten-containing coating compositions using accelerators
    Patent number: 5653790
    Abstract: Zinc phosphate aqueous coating compositions containing tungsten and using an accelerator which is an oxime, hydroxylamine sulfate or a mixture thereof are disclosed. The accelerators are environmentally friendly and stable in the acidic environment of zinc phosphate coating compositions so as to enable formation of a one-package system. The tungsten component avoids the use of nickel or cobalt ions in the compositions which are environmentally objectionable.
