Description and Uses
Zinc oxide, ZnO, is a reactive white pigment prepared by vaporizing
metallic zinc at a temperature of about 900°C in the presence of oxygen.
As a pigment, ZnO is basic in nature and can react with certain types
of acidic paint resins resulting in the formation of a brittle film on
drying. Formation of such films leads to premature failure of paint. For
this reason as well as because of its low RI,ZnO cannot compete
for the hiding power of TiO2.
Consequently, ZnO is rarely used as the
sole pigment in modern coatings, although it finds some use in admixture
with other pigments. ZnO is used in exterior house paints as a
fungicide and in some can linings as a sulfide scavenger.
