As a kind of constitutional pigment, high gloss barium sulfate is widely used in the coating industry, advertising and printing industry. In actual use, it can improve the thickness, abrasion resistance, water resistance, heat resistance, surface hardness, impact resistance and other important functions of the coating film. In addition, extinction barium sulfate at light wavelength of 300-400 μ It has high reflectivity in the range of m, can protect the paint film from light aging (to prevent fading), and is an effective and cheap white inorganic light stabilizer. Ultrafine barium sulfate made by special process has many characteristics that other similar products do not have. Its needle like crystal structure makes it a good matting agent and can enhance the leveling property of the coating. It can be used as a reinforcing agent in self-cleaning coatings; Because of its low oil absorption and high filling capacity, it can reduce the cost of coatings and can be used for water-based coatings, primers, intermediate coatings, oily coatings, etc. When it is used to replace 10% - 25% titanium dioxide in waterborne coatings, the whiteness is increased and the hiding power is not decreased.

Thickness, abrasion resistance, water resistance, heat resistance, surface hardness and impact resistance of the coating film. It is also applicable in the printing industry. Especially in the printing of outdoor advertisements.

The extinction barium sulfate is a name in the chemical industry. It is also called barite powder. Barite is mainly composed of barium sulfate. Because the product is widely used in industrial products; Paint, paint, plastic, rubber, ink, ceramics, can play a role in matting or matting, so it is called matting barium sulfate. As a special filler. Its application can replace or reduce the use of matting agent and effectively reduce the cost. Because its fine particle size matches well with the film thickness, it can achieve a satisfactory balance between the extinction efficiency and the surface smoothness. The resin does not produce differences in curing reaction, and is not afraid of baking. The matt effect is stable. It also does not take advantage of the difference in curing speed to produce uneven shrinkage to obtain the extinction effect.

The matting barium sulfate is used to process the selected barite by pure physical and chemical processing means, so it has four advantages:

Advantages: 1. Brighter color: matt barium has good dispersibility and great hiding power. It can also be used as the carrier of pigments to disperse pigments to obtain uniform color; High purity whiteness makes the tone more bright and pure; The fine crystal structure and high refractive index make the color more rich and full.

Advantages 2. More stable system: good chemical inertness of extinction barium keeps the basic environment of various systems stable; Superfine particles have strong surface energy, good compatibility, and can be organically cross compounded with other materials to enhance the adhesion; Evenly dispersed differential monomers are stably suspended in the system without flocculation or precipitation.
