High whiteness lithopone BA311
1. The use of lithopone:
1. It has good heat resistance, can improve weather resistance, prevent algae, reduce costs, and has excellent whiteness with excellent hiding power.
2. Lithopone has more uses than zinc sulfide. Similar in structure to zinc sulfide, it contains barium sulfate and has slightly lower durability. Poor chalking resistance. The price is cheap, so it can partially replace titanium dioxide.
3. Lithopone can be used for coloring paint, ink, rubber, etc.
2. Lithopone:
White crystalline powder. It is a mixture of zinc sulfide and barium sulfate. The more zinc sulfide, the stronger the hiding power and the higher the quality. Lithopone, also known as lithopone, has a density of 4.136～4.34 g/cm3 and is insoluble in water. It will easily decompose to produce hydrogen sulfide gas when exposed to acid, but will not work when exposed to hydrogen sulfide and alkaline solutions. It becomes light gray when exposed to ultraviolet rays in the sun for 6 to 7 hours, and restores its original color when placed in a dark place. It is easy to oxidize in the air, and agglomerates and deteriorates after being damp.
