Asterion will feature its Technicoat ZNBL 360 VCM, a ROHS-compliant, corrosive-resistant passivate for use over zinc and zinc/nickel-plated deposits. The passivate produces a clear, blue, bright finish said to offer more than 120 hrs. to white corrosion over zinc and zinc-nickel deposits. The trivalent passivate operates economically at room temperature at traditional passivate concentrations and is controlled using wet chemical methods. According to Asterion, it contains no chelating products and does not present waste treatment problems.
