PRODUCT LIST
BARIFINE Series
■Overview
Sakai Chemical's BARIFINE is a series of barium sulfate products consisting of grades with different particle sizes ranging from 0.01 to 0.1μm.
BARIFINE is mainly used for coatings for automobiles and consumer electrical appliances, catalysts, and other applications.
BARIFINE exhibits excellent transparency after dispersion and improves the gloss of the coating films. At the same time, it improves the coloring of organic pigments, the orientation of pearl pigments and aluminum flakes, and the jet blackness of carbon black.

BARIACE Series
■Overview
BARIACE exhibits excellent dispersibility and is used for coatings and inks.
The surface treatment grade B-30 series is characterized by ready dispersibility achieved by improving its affinity for plastics and lets you select the pigment pH, organic treatment, and more according to the plastic.
Both B-50 and B-60 series have high whiteness grades and are widely used in plastic applications.

For Paint, Ink, and Plastics
■Overview
Barium sulfate is an extremely chemically stable compound with high heat, chemical, and water resistance. It is used as a general extender pigment due to its high true specific gravity and refractive index equivalent to plastic.
Especially, barium sulfate with extremely fine particles has characteristics to contribute to improving dispersivity and chromogenic of colored pigments, the orientation of bright pigments, and smoother coating.
In addition, we also offer grades that are suitable for hygienic products and medical use that are compliant with standards for quasi-drugs raw materials.
