    Abstract: 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.

    Abstract translation: 本公开提供了经处理的无机颜料,通常为二氧化钛颜料,其包含表面积为约30至约75m 2 / g的无机颜料; 其中所述颜料表面用包含聚链烷烃烷烃或聚链烷醇胺的有机处理剂以基于处理的颜料的总重量计至少约1.5%的量处理; 其中经处理的无机颜料具有约7至约11的RHI(大鼠孔指数)。经处理的无机颜料具有更好的流动特性,并且通常较少的团块。
