ABSTRACT:
A flushing solution containing: a) a solvent component, b) an alkaline source; and c) a corrosion inhibitor component is provided. The solvent component preferably contains an alkoxylated aromatic alcohol. The corrosion inhibitor component may contain a fatty acid salt, a mixture of an aliphatic phosphate ester and a buffering agent such as boric acid or phosphoric acid, a mixture of a fatty acid salt, aliphatic phosphate ester, and buffering agent, or a mixture of a fatty acid salt and buffering agent. Alkanolamines are preferably used to form the fatty acid salt and/or as the alkaline source. The flushing solutions can be prepared in stable concentrated form and are useful for removing coatings such as paint from substrate surfaces.
