Abstract
This invention covers a formulation providing protection against corrosion in liquid and vapor phase. Such formulations are used in applications where engine parts or fuel cell systems are subjected to a 'running-in' or 'hot-test' prior to final assembly or storage. The invention includes a concentrate as well as a dilute solution. The synergistic combination of inorganic ammonium derivatives in combination with monocarboxylic or dicarboxylic acids increases the period of protection. This enables storage for a longer period when the engine parts are shipped or stored prior to assembling. The use of the described invention pre-conditions the metal surface and provides protection even if afterwards the liquid is almost completely removed.
