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.

Features
Cost-effective
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.
