Publication number: 20100270494Abstract: This invention relates to a solution that provides protection against forms of corrosion. Such solutions are intended for use in applications where cooling system parts are hot tested or the engine is run-in prior to it being stored and/or assembled in the final vehicle or engine configuration. The invention includes a concentrate as well as a dilute solution made from the concentrate. The synergistic combination of inorganic ammonium derivatives in combination with monocarboxylic or dicarboxylic acids has proven to dramatically increase the period of protection, thus enabling storage for a longer period when the engine parts are shipped or stored prior to assembling. The use of the described invention shows a pre-conditioning of the metal surface and provides protection even if afterwards the liquid is almost completely removed.Type: ApplicationFiled: May 27, 2009Publication date: October 28, 2010Inventors: Jurgen P.
