ABSTRACT:
The corrosion inhibiting systems comprise at least one of the following: sodium fluorophosphate, and a water soluble salt of phosphonic acid derivatives having the general formula R.sub.n R.sub.1 N(CH.sub.2 PO.sub.3 H.sub.2).sub.2-n wherein R.sub.n and R.sub.1 are each independently selected from a member selected from the group consisting of alkyl, aminoalkyl and N-hydroxyalkyl and n is an integer selected from 1 and 0. The methods comprise laying on a surface a system as defined above. The invention also discloses deicers, paints and other corrosion inhibitors in numerous carriers. Products containing at least residual amounts of a system as defined above are also disclosed.
