 Sep 12, 2024|View:409


Precipitated barium sulfate SG series is a high-end precipitated barium product synthesized and produced by Yunfu Hongzhi New Materials Co., Ltd. (Ambition®) by advanced barium carbonate-sulfuric acid method. Its biggest feature is its large particle size, good matte and light scattering ability, no absorption of visible light, extremely high whiteness and reflection coefficient, and its L value exceeds 99%, which is more pure white and color neutral than natural barium sulfate.

Product Advantages:

1. 98% content of micron-grade precipitated barium sulfate, with particle sizes ranging from 3 to 8 microns.

2. Excellent matting effect, providing high-quality matte and semi-matte effects.

3. Low oil absorption, good dispersion, high solid filling, and weight increase effects.

4. Weather-resistant, acid and alkali-resistant, and chemically inert.

5. The L value in the Lab color values reaches up to 99%, with good light reflection performance and high whiteness.

The median particle size ranges from 3 to 8 microns, with a concentrated distribution, which results in the SG series of precipitated barium sulfate having low oil absorption, good dispersion, non-agglomeration, and the ability to shorten grinding and dispersion time. Even at higher concentrations, it maintains good flow properties. Additionally, it has excellent suspension characteristics, avoiding layering and hard sedimentation.

precipitated barium sulfate in matte and semi-matte coating and ink

The matting effect of the SG series of precipitated barium sulfate is outstanding in matte and semi-matte coating and ink systems. Its specific particle size and square-shaped crystals effectively scatter incident light, directing it in multiple directions, reducing specular reflection. The crystal shape also increases the micro-roughness of the coating surface, creating a discontinuous surface in the paint film, thus producing a soft matte or high-end semi-matte effect.

The soft matte or high-end semi-matte effect plays a unique role in applications that avoid high-gloss surfaces, such as indoor decoration, matte metallic automotive paints, and high-value artwork.

Furthermore, the SG series of precipitated barium sulfate is acid and alkali-resistant, chemically inert, and suitable for weather-resistant and chemical acid and alkali corrosion-resistant paint systems, such as ship bottom paints and can coating systems, protecting the substrate from corrosive substances like seawater and acid rain.
