Ultra fine barium sulfate has a superior isolation effect on the particles of white or colored pigments, keeps a certain distance from each other, and improves the pigment efficiency. In particular, the barium sulfate particle is small and has excellent performance, which can free the network gap formed by titanium dioxide in ink and coating, greatly improve the weather resistance of ink and coating and improve the quality of paint; And its impurities are very few, and there will be no chemical reaction between impurities and organic substances in ink and coating; In addition, it has excellent dispersion in all paints, which can prevent paint agglomeration, improve paint quality and increase fluidity.
