Abstract
An aqueous metal treatment composition designed to improve adhesion and corrosion resistance of the metal surface includes an organofunctional silane in combination with a fluorozirconic or fluorotitanic acid, methanesulfonic acid and nitric acid. The methanesulfonic acid acts to reduce sludge formation. Preferably, the composition also includes a fluorosilicic acid which likewise reduces sludge and improves corrosion resistance.
