Abstract

Titanium Dioxide and other pigments or powders processed by this present process are smoothly discharging, low dusting, agglomerated, compaction resistant, extremely friable, and fully dispersible, and the process for the production of smoothly discharging pigment or powder consists of gently blending in the presence of an air flow and an electrostatic charge where said pigment or powder is agglomerated with or without a treated or non-treated seed particle of the same or similar pigment whereas said pigment or powder in accordance with the invention yields a composition of substantially spherical particulate that has a pseudo-particle size of 0.1-5.0 mm in the form of smoothly discharging, low dusting, non-sticky, agglomerated, compaction resistant pigment or powder, in which said pigment or powder particles are 80% -99.9% by weight, pigment, and in which the pigments or powders are compatible with inks, paints and plastics, and can be readily dispersed and incorporated into the same.
