ASTM D79-86(2014) PDF

Scope: 3.1 Zinc oxide functions as both a chemical and a pigment. It is used in a variety of applications including rubber, paint, reprography, glass, chemicals, etc. In paint, it contributes to mildew protection, ultraviolet absorption, hiding power, and neutralization of acids formed upon oxidation of the paint film.

1.1 This specification covers the pigments commercially known as “zinc white” or zinc oxide. The pigments may be purchased in the dry form or as a paste in oil.

Note 1: Zinc oxides are used in many industries. For additional information, see Classification D4295 and Test Methods D4315 for descriptions of zinc oxide use in rubber compounding.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
