Zirconium Pretreatment
Q. The zinc oxide pretreatment we use requires a primer for
outside parts. What about zirconium pretreatment? Could
you provide details about the setup, installation costs,
benefits and limitations? Ours goes through a 5-stage system
and then through a powder coating process.
A. A zinc oxide coating will not provide significant corrosion
resistance, as it appears you have discovered. The zirconium
oxide conversion coating should provide a superior coating
for corrosion resistance and overall performance of your
powder coating. The zirconium oxide process is generally
performed at a lower temperature, so it should result in a
cost savings related to a lower energy usage. Additionally,
the tank will not produce significant sludging (as would be
the case with a zinc phosphate conversion coating process).
The coating weight is generally low, but still produces high
performance results. Another potential benefit is that it
may produce smaller environmental footprints in more
than just the lower energy usage. It will likely generate a
lower amount of chemicals that need disposal with a lower
toxicity. One potential difference is the need to use water
with possibly a higher purity than you may otherwise use
with a traditional zinc oxide or phosphating conversion
coating process.
