Abstract

Concentrate for activating and refining bath employed in processes of zinc phosphatization, characterized by the fact that it is based on an aqueous dispersion containing from 2 to 20% by weight of Jernstedt salts, the concentration of titanium in the dispersion consequently being from 140 to 10,000 ppm of Ti, this dispersion in addition containing:
- a proportion of from 0.2 to 8% by weight of at least one dispersing or sequestering agent and - a proportion of from 0.05 to 7% by weight of at least one thickener based on polysaccharide.
