ASTM D607-82(2012)

Standard Specification for Wet Ground Mica Pigments

ABSTRACT
This standard specification covers wet ground mica pigments for use in the manufacture of protective coatings. Pigments shall be made by wet grinding muscovite mica. Properties such as density, moisture, grit, coarse particles, residue, ignition loss, and color shall conform to the requirements of the specification.
SCOPE
1.1 This specification covers two types of finely divided muscovite mica, commercially known as wet ground mica, suitable for use in the manufacture of protective coatings.
