TREATED INORGANIC PIGMENTS HAVING IMPROVED BULK FLOW |
摘要 |
<p>The disclosure provides a treated inorganic pigment, typically a titanium dioxide pigment, comprising an inorganic pigment having a surface area of about 30 to about 75 m2/g; 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%, based on the total weight of the treated pigment; wherein the treated inorganic pigment has a RHI (rat hole index) of about 7 to about 11. The treated inorganic pigments have better flow characteristics, and generally fewer lumps.</p> |
