 Jan 14, 2025|View:90

The precipitated barium sulfate M-700 from Yunfu Hongzhi New Materials Co., Ltd. exhibits numerous outstanding characteristics by virtue of the organic surface modification technology. Its product particle size is as fine as 0.7μm, with a narrow particle size distribution, good chemical stability, high activation degree, excellent dispersibility, high whiteness, and low oil absorption. In various fields such as coatings, inks, pigments, color pastes, and modified plastics, its quality is comparable to that of imported similar products, and it can be regarded as an excellent synergistic agent for titanium dioxide to reduce costs and increase efficiency.

As a functional powder product, when the precipitated barium sulfate M-700 is incorporated into the coating system and used together with titanium dioxide, the two complement each other and produce wonderful synergistic effects. With its assistance, the whiteness of titanium dioxide is further enhanced, the color development becomes more precise and dazzling, and the glossiness is also increased. At the same time, it can enable titanium dioxide to achieve better dispersion, greatly reducing the time cost required for dispersion and grinding. Moreover, at the microscopic level, it builds a stable interval support structure for titanium dioxide particles, significantly strengthening the impact resistance of the coating.

During the process in which the precipitated barium sulfate M-700 and titanium dioxide particles exert their synergistic effects, if uniform dispersion can be achieved and specific arrangement rules are followed, the key factor of transparency will be activated. This is the inherent reason for the simultaneous increase in the glossiness and whiteness of the products. Even in the red pigment system, this exquisite principle is equally effective.

The 0.7-micron precipitated barium sulfate M-700 provides all-round synergistic assistance for titanium dioxide in coating applications, mainly covering the following highlights:

① Optimization of Fluidity and Dispersibility

Principle: In the coating mixing process, the precipitated barium sulfate M-700 acts as a "master blender", helping titanium dioxide and other pigments to disperse evenly in the coating substrate, preventing pigment agglomeration and making the fluidity and construction performance of the coating brand new.

Application Effect: During construction, the coating can be spread easily and smoothly, the coating layer is smooth, flat, uniform, and fine, and both the construction efficiency and quality are significantly improved, and defects such as sagging and orange peel disappear.


② Secret to Whiteness Enhancement

Principle: The characteristics of the precipitated barium sulfate M-700, such as its fine and uniform particles and narrow particle size distribution, complement those of titanium dioxide. Coupled with its relatively high refractive index, when the two are used in combination, the whiteness of the coating is significantly enhanced, while the hiding power remains unaffected, and the color becomes more vivid and uniform.

Application Effect: When formulating coatings, the M-700 and titanium dioxide work in harmony. Not only can the hiding performance of the coating be maintained, but it can even be further improved. In this way, while ensuring the quality of the coating, the cost is also quietly reduced.


③ Cost Control Strategy

Principle: Although titanium dioxide has excellent performance, its price is relatively high, while the price of precipitated barium sulfate is affordable. By adding an appropriate amount of precipitated barium sulfate M-700, under the premise that there is no obvious reduction in coating performance, the amount of high-priced pigments such as titanium dioxide can be skillfully reduced, and the production cost of the coating drops immediately.

Application Effect: While safeguarding the foundation of coating quality, the cost performance of the product is greatly improved, enhancing market competitiveness, especially meeting the precise cost control requirements in large-scale coating production scenarios.


④ Strengthening Chemical Stability

Principle: The precipitated barium sulfate M-700 itself has excellent chemical stability and outstanding weather resistance. It is like a loyal guard for titanium dioxide, preventing it from reacting with external substances and effectively reducing the impact of adverse factors such as light and gas on titanium dioxide, enabling the coating to maintain excellent performance in any environment and significantly extending its service life.

Application Effect: When applied to outdoor coatings and coatings with strict requirements for weather resistance, after adding M-700, the weather resistance and chemical stability of the coating are significantly improved, and problems such as fading and chalking are almost eliminated.


⑤ Guide to Increasing Solid Content

Principle: The precipitated barium sulfate M-700 has an extremely low oil absorption. After being added to the coating formula, it can steadily increase the solid content of the coating, reduce the linear expansion rate, and the content of volatile organic compounds (Voc) also decreases accordingly.

Application Effect: In coating application fields that require high wear resistance and impact resistance, such as industrial floor coatings and automotive coatings, after adding M-700, the weather resistance and environmental protection attributes of the coating are mutually enhanced.
