Precipitated Barium Sulfate is a high brightness, low oil absorption, inert extender that is well suited for a variety of application including powder coatings, thermoplastics, elastomers, fiber, paper, ink and pigment preparations.
Precipitated Barium Sulfate has a Mohs hardness of 3 and is very low in abrasion. It exhibits a continuous, high diffuse reflectance of light, not only in the visible range, but also far into the UV and IR ranges. It is the ideal extender of colored systems. In coatings, Precipitated Barium Sulfate is recommended in high gloss, acid-resistant formulations.
Precipitated Barium Sulfate is inert, resistant to light and weathering, and insoluble in water, acids, alkali and organic media.
