Zinc chromates are used for decorative, and as anticorrosive, yellow
paints. This pigment has the advantage of being nontoxic and, furthermore,
its color does not change by exposure to sulfur containing atmospheres.
It is characterized by excellent light-fastness, but its use is
restricted because of poor opacity and poor tinting strength. The color
stability of zinc chromate when exposed to lime permits its use as a pigment
in paints for plaster and concrete.
