Corrosion inhibitors containing a mixture of one or more water soluble tetraborate salts and one or more water soluble condensed phosphate salts are non-toxic and are more effective than either of the components alone. These compositions containing both tetraborates and condensed phosphates are also more effective than such prior art inhibitors as nitrites and ethanolamine-based inhibitors.

Anticorrosive agents and use thereof

A method for stabilizing the electrolyte content of latex composition baths in which, preferably, the bath is flowingly contacted with the outside of a tubular filtration membrane having pores smaller than the latex micelles, and partly deioized water flows through the center of the tubular membrane at a rate sufficient to cause a pressure differential and thus effect ultrafiltration removal of electrolytes.

Electrolyte stabilization of latices

A process for increasing the anticorrosive properties of an autodeposited coating wherein after the bath but before the curing, metallic chromate salts are formed in situ by first rinsing with metallic non-chromate water soluble salts and then rinsing with a chromium compound.
