TREATED INORGANIC PIGMENTS HAVING IMPROVED BULK FLOW AND THEIR USE IN COATING COMPOSITIONS

摘要

The disclosure provides a coating composition comprising a treated inorganic pigment, wherein the treated inorganic pigment comprises an inorganic pigment comprising a pigment surface area of about 30 to about 75 m2g; wherein the pigment surface is treated with an organic treating agent comprising a polyalkanol alkane or a polyalkanol amine, present in the amount of at least about 1.5%, and wherein the treated inorganic pigment has a RHI (rat hole index) of about 7 to about 11.
