Lithopone is an inorganic white pigment, obtained from co-precipitation of Zinc sulfide (ZnS) and Barium sulfate (BaSO4). Titanium Dioxide (TiO2) has replaced Lithopone as a white pigment in majority applications as TiO2 is more durable. However, it is much cheaper than TiO2 and has advantages such as low binder requirement and good dispensability. As a white pigment, it can improve the substrate's weather resistance, and improve the fungicidal properties of paint formulations. Some of the major applications of Lithopone include manufacturing of paint pigments, plastic & rubber products, paper, printing inks, cosmetics, and leather & linoleum products. It is commercially available under names such as pigment white 5, Barium zinc sulfate sulfide, Becton White, C.I. 77115, Charlton White, Enamel White, and Zincolith. On the basis of content of ZnS, Lithopone is available at 28%-30% Lithopone and 60% Lithopone.
It is a white crystalline powder, which is a mixture of zinc sulfide and barium sulfate. The more zinc sulfide it contains, the stronger the hiding power and the higher the quality. The density of lithopone is 4.136~4.34/cm3 and it is insoluble in water. It easily decomposes when exposed to acid to produce hydrogen sulfide gas, but does not work when exposed to hydrogen sulfide and alkaline solutions.
The precipitation of titanium dioxide involves the reaction of titanium sulfate with an alkaline solution to form titanium hydroxide, which is then calcined to produce titanium dioxide. The precipitation process is crucial for achieving the desired particle size distribution, crystallinity, and purity of the final product.
Though the regulated use of titanium dioxide in food products is legal in the U.S. and Canada, it's banned in some other countries, notably throughout Europe. In May 2021, the European Food Safety Authority announced that titanium dioxide can no longer be considered safe as a food additive.
- Another important property of MHEC is its ability to form films upon drying
methyl hydroxyethyl cellulose mhec. This makes it useful in the production of coatings, adhesives, and printing inks. For example, MHEC can be used as a binder in water-based paints and varnishes, providing excellent adhesion and durability. It can also be used as a film former in pressure-sensitive adhesives, allowing for strong bonding between surfaces without leaving residue upon removal.
4)Methyl Cellulose has a noticeable impact on the workability and adhesion of mortar. Adhesion here refers to the adhesive force felt between the worker's application tool and the substrate. Greater adhesion leads to higher shear resistance and requires more force during application, resulting in decreased workability. In terms of cellulose ether products, Methyl Cellulose exhibits moderate adhesion.
Tell your doctor and pharmacist about all of your drugs (prescription or OTC, natural products, vitamins) and health problems. You must check to make sure that it is safe for you to take hydroxypropyl methylcellulose with all of your drugs and health problems. Do not start, stop, or change the dose of any drug without checking with your doctor.
