EPi's E-Passivate Blue is a single component bright blue, trivalent chromate dip.
EPi has developed an entire line of trivalent chromate dips that outlast the traditional hexavalent dips used. E-Passivate offers salt spray resistance up to 150 hours versus 16-24 hours with hexavalent dips. The corrosion protection of E-Passivate is absolutely incredible with up to 240 hours resistance to red rust.
E-Passivate Blue can be used as a conversion coating for zinc, zinc-die-cast and can replace hexavalent sealers for nickel. It is operator friendly, long lasting, and just another solution from EPi that's simply superior!
