Abstract
The present invention relates to an improved titanium containing phosphate composition and a process for preparing the titanium containing phosphate composition. The composition in the form of a dilute aqueous dispersion is useful as a rinse conditioner for activating ferrous, zinc and aluminum metal surfaces prior to the application of phosphate conversion coatings. The rinse conditioner forms stable baths and can be used for activating metal surfaces for extended periods of time.
