ASTM D476-00(2011)

Standard Classification for Dry Pigmentary Titanium Dioxide Products

SIGNIFICANCE AND USE
This classification is given as an aid in determining the fitness for use of a titanium dioxide pigment for a coating application. It is limited to dry, hiding pigments. It excludes pigment dispersions, and non-hiding specialty titanium dioxide products.
SCOPE
1.1 This classification describes seven types of dry pigmentary titanium dioxide products, grouped by composition, typical end use application, and some performance properties.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
