Chemetall Coatings, Zinc Phosphate Process - Spray/Immersion CrysCoat MP

CrysCoat MP is a nickel-containing, zinc phosphate process for steel, hot dip galvanized steel, galvanneal and electrogalvanized steel applied by spray or immersion. Small amounts of aluminum may also be processed through CrysCoat MP, although coatings are normally developed on aluminum only with special additives. The dense, fine-grained zinc phosphate coatings produced by CrysCoat MP improve the performance of electrophoretic, powder, solvent- borne and water-borne paints. CrysCoat MP meets the requirements of Federal Specification TT- C-490 Type 1 and Boeing Process Specification BAC 5810 Type III. Coating weights of about 150-500 mg/ft2 (1.5-5.0 g/m2) can be produced with CrysCoat MP, depending on the parameters and on the particular grain refining activator used in the rinse prior to CrysCoat MP.
