How to strip zinc from stamped metal sheet before e-coating





August 3, 2012

Q. Dear all,
I would like to know any suggestion to strip off (blue) zinc plated surface to prevent uneven surface appear after E-coat finishing.
I tried with sulphuric acid and HCl but it seems like both cause me other problems.
Appreciate input from fellowship all over the world.
Thanks.

A. Hi KC.
I've stripped electro-galvanized stamped parts from steel sheets followed by CED coating without much problem . I use 30% HCL , once the fizzle stops, they are quickly removed, thoroughly rinsed and immediately proceed to CED coating. The appearance of the CED coating is certainly much more smoother with the galvanize removed.
