摘要： Disclosed is a high etch cleaner for aluminum and aluminum alloy substrates that leads to enhanced corrosion protective performance of a variety of anti-corrosion pretreatments. The cleaner comprises very low levels of silicate of from 0 to 250 ppm, 50 to 500 ppm of at least one chelator selected from EDTA or its salts, NTA or its salts, DTPA or its salts, iminodisuccinic acid or its salts, EDDS or its salts, tartaric acid or its salts, or a mixture thereof, and has a high pH of from 11.0 to 13.5. Preferably the cleaner is used to etch from 0.5 to 4.0 grams per meter squared from the substrates. Substrates treated with the cleaner and then coated with a variety of anti-corrosion pretreatments and outer coatings show enhanced corrosion resistance compared to substrates cleaned with standard cleaners that have low etch rates, high silicate levels and no chelating agents followed by anti-corrosion pretreatments and outer coatings.

摘要： Disclosed is a pretreatment composition for a metal that provides enhanced corrosion resistance, enhanced paint adhesion and reduced chip damage. The pretreatment is also cleaner because it is based on zirconium rather that zinc phosphates. The pretreatment coating composition in use preferably comprises 50 to 300 parts per million (ppm) zirconium, 0 to 100 ppm of SiO2, 150-2000 ppm of total fluorine and 10- 100 ppm of free fluorine, 150 to 10000 ppm of zinc and 10 to 10000 ppm of an oxidizing agent and has a pH of 3.0 to 5.0, preferably about 4.0. The coating composition can optionally include 0 to 50 ppm of copper. The suitable oxidizing agents can be selected from a large group. The pretreatment coating composition greatly enhances the corrosion resistance of a wide variety of metal substrates including cold rolled steel, hot rolled steel, stainless steel, steel coated with zinc metal, zinc alloys such as electrogalvanize steel, galvalume, galvanneal, hot dipped galvanized steel, aluminum alloys and aluminum substrates.
