Products Description
A mixture of zinc sulfide and barium sulfate, also known as zinc barium white, white crystalline powder. It is a mixture of zinc sulfide and barium sulfate. The more zinc sulfide it contains, the stronger its covering power and the higher its quality.
Performance: insoluble in water, similar to zinc sulfide composition in structure, containing barium sulfate composition, slightly poor durability, good heat resistance, algae proof, has excellent covering power, not acid resistance, poor powder resistance, moisture easy caking metamorphism, cheap price, so it can partially replace titanium dioxide (titanium dioxide) use.
Features: B-301 its covering power is stronger than zinc oxide, weaker than Anatase, good heat resistance.
B-311 has better coloring power and covering power than 301, and has better dispersion.
