Specialized For Painting Overview

Precipitated Barium Sulfate

Specialized for Painting

The precipitated barium sulfate has strong chemical inertness, good stability, acid and alkali resistance, insolubility in water, ethanol, organic solvents, moderate hardness, high whiteness, high gloss and the ability to absorb the harmful x-ray, etc. It is a kind of material with environmental protection function. Onmillion Group has its own barium sulfate invention patents, reaction technology and advanced grinding technology different from others’, which help in particle size distribution control of ONMILLION precipitated barium sulfate to a very narrow level, and along with the various surface treatment, the surface has a good affinity.

Product Features


ONMILLION precipitated barium sulfate has a high reflection coefficient even in a very wide spectrum, so its appearance is white powder with neutral color. This makes it able to maintain the original pigment vividness and hue. Most pigments are easy to form aggregates, which will weaken the tinting strength of the pigment. Whether it is water-based paste, solvent paste or universal paste, by using ONMILLION precipitated barium sulfate it will significantly reduce the flocculation problems in the preparation of a variety of pigments, increase steric hindrance or charge repulsion stabilized pigment, and improve its cost-effectiveness. Moreover, it is able to effectively reduce the amount of use of various pigments, serving as an alternative to pigments, including titanium dioxide, color pigments and carbon black, etc..

Maximized Gloss

ONMILLION precipitated barium sulfate has a good dispersibility, so the coating with ONMILLION precipitated barium sulfate has high gloss and rheology even at higher concentrations.

Reducing the solvent content

ONMILLION precipitated barium sulfate has low oil absorption, and it can effectively increase the solid parts of the paste, and reduce the amount of solvent with almost no impact on the viscosity, and reduce VOC.

Shortening the grinding time

ONMILLION precipitated barium sulfate used in paint preparation can effectively reduce the flocculation problems in the preparation of a variety of pigments, not only saving raw materials but also effectively shortening the time of grinding and dispersion.

Good weatherability

ONMILLION precipitated barium sulfate has a strong light reflection ability in the ultraviolet wavelength range with synergy with TiO2, having good sunscreen resistance and weathering resistance.

Improving the mechanical properties

Coatings, added with ONMILLION precipitated barium sulfate, has better interlayer adhesion and coating hardness.
