A&P here. Zinc chromate is used as a primer on aluminum surfaces as a conversion process to inhibit corrosion. Since nearly all modern aircraft skins and structures are made from aluminum, this compound and its derivatives are the most common primers seen in aircraft manufacturing.
The Problem. On the companyâs Houston, TX coating line, zinc phosphate is applied to steel coils to serve as a protective coating. A by-product of the coil coating process is a sludge formed from the zinc phosphate, water and etching compound, which ends up settling to the bottom of the coating lineâs tank unit.idwest accepted this challenge and after completing on-site material tests, concluded that the CentraSep system would work. Precoat installed the centrifugal liquid solid separator as part of the pretreatment section of it coil coating in 2002 and put it to work removing the zinc phosphate from the process water.
