Will solvent-based rust preventive agent
dissolve Chromate Sealer?
++
Hi all,
We applied Chromate Sealer on the blue chromating of the zinc
plating as topcoat. To enhance the corrosion resistancy, we have
additional of anti-rust agent (strong solvent-based) dipping before
handling.
These chromate sealer layer (with blue zinc as undercoat) is
potential to external rubbing/scraching/wearing etc during
assembliment, handling and storage. I'd like to know if the
solvent-based anti-rust agent would weaken (even dissolve) the
chromate sealer, which is an inorganic protective paint to the zinc.
Thanks for advice.

If the solvent base is acid it will strip the coating to some
extent - if it is only solvent then probably it will have no effect.
