<p>Stabilization of the phosphating quality achieved after a surface conditioning treatment with an otherwise conventional composition containing dispersed colloidal titanium, and other benefits, is achieved by causing the aqueous composition to flow at a rate of at least 80 meters per minute for at least 10 minutes after make-up, in order to achieve optimum titanium particle size and homogeneity of the composition.</p> |
