Product Name: Micronized Barium Sulfate
Technical Description: Micronised Barytes , BaSO4, Barytes Powder, Natural Barium Sulphate
Appearance: White powder
CAS Registry NO.: 7727-43-7
Physical and Chemical properties: It can completely retain the crystal form of barite. It has large specific surface area,surface atom quantities and surface energy so that there is great change in optical performance, adsorptive force, hiding power and flowing property, which completely surpasses the original excellent characteristics of barium sulfate, so that micronized barium sulfate becomes an excellent body paint. It has good dispersibility and hiding power; when it is used as the pigment carrier, it can highly disperse the pigment so that the paint has even color 93%-96% super-whiteness makes the paint hue to be brighter; Special crystal structural characteristics and high refractive index makes the color be more plentiful and full. It has excellent chemical inertness and better compatibility; It can easily organically combine with other materials to enhance the adhesion; The suspension system is very stable; It does not generate flocculation or precipitation, It make the film and the substrate to combine more firmly; Uniform micronized particles make the film smoother and more durabl. The special properties such as excellent chemical inertness, resistance to acid and high temperature have greatly improved the paint weatherability. Very low oil absorption can increase the critical material volume concentration of paint, and save more resins and binders.
