Chromating provides a refined appearance and increased corrosion resistance, along with greater resistance to fingerprint staining. Chromating is an excellent pre-paint base, increasing paint adhesion and imparting color to metal for coloring effect or identification. Chromates are a soft coating that, when wet, are easy to scratch. However, once dry, the coating becomes more durable with age. Hexavalent chromates are damaged by heat over 150 degrees. We chromate directly on zinc die castings and zinc plated parts. Corrosion resistance is increased with the use of chromates and sealer:


  • Clear (bright blue) High Corrosion-Resistant Trivalent Chromate (hex-free)
  • Yellow (iridescent) Dichromate (hexavalent)
  • Yellow (iridescent) Trivalent (hex-free)
  • Post Chromate Silicate Sealer

Please view our Environmental page for more information about trivalent/hexavalent-free chromates, in addition to RoHS, ELV, and EEE compliant finishes.
