Abstract (en)
[origin: WO02061176A1] An aqueous surface conditioner for use in a phosphating treatment is provided which contains crystals having an average diameter of 5 mu m or less in an amount of at least 0.1 g/L. The crystals are selected to have a two-dimensional epitaxy that matches within 3 % of misfit with the crystal lattice of one phosphate coating selected from among (1) hopeite /Zn3(PO4)2<.>4H2O) and/or phosphophyllite (Zn2Fe(PO4)2<.>4H2O), (2) scholzite (CaZn2(PO4)2<.>2H2O) and (3) hureaulite (Mn5(PO4)2[PO3(OH]2<.>4H2O).
