Non-toxic Corrosion Protection Conversion Coats (UD268)

  • Chrome Free
  • Non-toxic
  • Pigments available in many colors
  • Works well in multiple applications
  • Protection of metal and other surfaces from corrosion equal to chrome
  • Any application where chrome cannot be used to protect metals
  • Easy application and use

The invention is an aqueous conversion coating composition for treating steel substrates to provide a conversion coating that protects the steel from corrosion. The conversion coating composition comprises: a) a source of aluminum ions; b) hexafluorozirconic acid or its salts; c) at least one pH adjuster; and d) optionally, a surfactant. The conversion coating composition provides a corrosion resistant coating on the metal surface and improves the adhesion of subsequently applied layers.
