Product Brief Introduction:

Hongzhi precipitated barium sulfate M-700 has the characteristics of small particle size, narrow distribution range, good chemical stability, high activation, good dispersion, high whiteness and low oil absorption. Can be widely used in a variety of coatings, plastic products, can significantly improve the product surface gloss, opacity, leveling, impact resistance and adhesion.

M-700 is not only a functional powder product, but also one that can be mixed with TiO2 (Titanium Dioxide), which can reduce the cost and increase the efficiency without changing the opacity properties.

Product Feature：

1. High gloss, after grinding by the sand mill, paint paste has high gloss and rheological properties.

2. M-700 can increase the solid content of the pigment paste and greatly reduce the amount of solvent. Due to its extremely low specific surface area, it has little effect on viscosity and also reduce VOC.

3. The usage of M-700 in preparation of various pigment pastes can not only save raw materials, but also greatly shorten the grinding and dispersion time, and achieve the established coloring force and the fineness of the scraper.

4. High purity, acid and alkali resistance, insoluble in water and any organic solvent, with good weather resistance.

5. Low refractive index, neutral color. In a wide spectrum, M-700 has a very high reflection coefficient,. Therefore, M-700 can maintain the original brightness and tone of the pigment.

6. No sulfide, no odor, no black spot impurities.

7. Can improve the rigidity, gloss, hardness and wear resistance of plastic products. It can increase the crystallinity of thermoplastic polymers, thereby improving the strength (especially the impact strength at low temperatures) and dimensional stability, but also improve heat resistance and reduce shrinkage.

Application:

precipitated barium sulfate M-700 is mainly used in paint, ink, pigment, color paste, modified plastics and so on.

In practical applications, the amount of M-700 in the paint paste needs to be determined according to the specific requirements and performance indicators. At the same time, in order to ensure the best performance, barium sulfate need to be surface treated, such as the using of coupling agents surface treatment to enhance its dispersity and adhesion in the resin matrix.

Pigment paste is a kind of liquid pigment dispersion, precipitated barium sulfate M-700 is used in the paint manufacturing process, it can simplify the paint production process and improve the efficiency. While using M-700, attention needs to be paid to the fineness, stability and compatibility with the resin to ensure the quality of the final paint product.

Suggestions:

precipitated barium sulfate M-700 is recommended to add 5 to 25% while grinding.
