Clear zinc plating essentially does mean colorless or transparent and is essentially a color choice which shows the natural metallic color of the zinc coating.
Clear zinc chromate.
Darker coatings generally provide more corrosion resistance.
Zinc plating in general can be broken into two primary steps.
Clear chromate withstands 16 24 hours in neutral salt spray while yellow withstands 96 hours.
What is clear zinc plating.
Additionally zinc chromate is highly toxic thus protecting the surface from proliferation of organic matter.
Even today chromate finishes including zinc chromate provide superior corrosion resistance.
However the coating color can also be changed with dyes so color is not a complete indicator of the process used.
Our zinc and chromate finishes are rohs compatible.

Zinc chromate is a corrosion resistant agent that is added to certain coatings.
Yellow or clear zinc chromate coatings yellow and clear sometimes called white essentially perform the same function as a superior corrosion inhibitor for your metal parts.
The protective effect of chromate coatings on zinc is indicated by color progressing from clear blue to yellow gold olive drab and black.
The first step is to add the zinc plating through the use of electrical current.
