The Application of Barium Sulfate in Paint
Barium sulfate is superior to most other filling powders and has characteristics such as low cohesion, low light dispersibility, and fine particles. Barium sulfate is particularly suitable for pigment topcoats, varnishes, spray paints, etc. It has chemical resistance and weather resistance. It is inert, insoluble in organic mediators such as water, acid, and alkali, and its excellent glossiness and particle fineness enable the topcoat to be maintained during long-term exposure. Barium sulfate is recommended for topcoats to increase surface hardness and color stability.
Barium sulfate has high filling ability and can be applied to all coating series, such as primers, thick paste coatings, and other types. Its low specific surface area, particle size distribution, and easy flowability make barium sulfate low in wear during processing. Barium sulfate is recommended for automatic primer surface layers, and even maintains good uniformity and smoothness during high filling.
