The Application of Barium Sulfate in Paint

硫酸钡优于其他大多数填充粉体，具有低凝聚性、光分散性低及颗粒精细等特点，硫酸钡特别适用于颜料面漆、清漆、喷漆等，具有耐化学性与耐候性。其惰性、不溶于水、酸、碱等有机中介，极佳的光泽性与颗粒的精细度使得面漆长期暴露中得到保持。硫酸钡推荐用于面漆，可增加表面硬度和颜色稳定性。

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.
