Zinc chromate

Zinc chromate, ZnCrO4, is a chemical compound containing the chromate anion. It is used industrially in chromate conversion coatings.

Its use as a corrosion resistant agent was applied to aluminium alloy parts first in commercial aircraft, and then in military ones. During the 1950s it was typically found as the "paint" in the wheel wells of retractable landing gear on U.S. Navy aircraft, not because of its glaring yellow-green color symbolizing anything, but to protect the aluminium from corrosion by sea salt.

When used as a pigment, it is known as Zinc Yellow or Yellow 36. It is highly toxic and rarely used in art anymore.
