description:
The invention is an aqueous conversion coating composition for treating steel substrates to provide a conversion coating that protects the steel from corrosion. The conversion coating composition comprises: a) a source of aluminum ions; b) hexafluorozirconic acid or its salts; c) at least one pH adjuster; and d) optionally, a surfactant. The conversion coating composition provides a corrosion resistant coating on the metal surface and improves the adhesion of subsequently applied layers.
