  • COLDIP® ALPASS 455 CS

    A concentrated light green liquid based on trivalent chromium technology used in the passivation of aluminum alloys, magnesium, zinc, and zinc alloys via immersion. It provides excellent corrosion protection and is an alternative to hexavalent chromium passivation and is suitable for post-treatment after anodic coating or as a pretreatment before lacquering, powder coating, or application of adhesives to the aluminum or aluminum alloy surfaces. COLDIP® ALPASS 455 CS will leave a clear, iridescent, or slightly light blue color on the aluminum surface (dependent upon aluminum alloy, concentration, time and temperature, or treatment of surface).
