Barium sulfate as an extender pigment widely used in paints to improve the thickness of the coating, abrasion resistance, water resistance, heat resistance, surface hardness, impact resistance, etc. plays a very important role. In addition, barium sulfate at a wavelength of 300-400μm
Within a high reflective film, can protect against photoaging, is an effective and inexpensive white inorganic light stabilizer. Using a special process made a lot of other similar products do not have the characteristics of ultrafine barium sulfate. Its needle-like crystal structure makes it an excellent flatting agents, and can enhance the flow and leveling of the coating, it can be used as a reinforcing agent in self-cleaning type coating; because of its low oil absorption, has a high filling amount, so allows the coating to reduce the costs that can be used in water-based paint, primer, intermediate coating, and oil paint. Use it to replace the 10% -25% of titanium dioxide in the water-based paint, the results improve whiteness, hiding power has not declined.
