Products Description

Lithopone is a white powder that is insoluble in water and non-toxic. Its pigment is also known as C.I.77115 or Pigment White 5.
Lithopone has good heat resistance. Applying a layer of Lithopone on an object can improve its weather resistance and prevent the growth of algae and moss.
Lithopone is also a low-cost, opaque white powder. Its light-blocking rate is second only to titanium dioxide.

Applications

Lithopone has many applications.
1. Paint: Because of its good hiding power, heat resistance, alkali resistance and fluidity, it is particularly effective for the production of varnished cloth for coloring pigments, which can extend the service life.
2. Ink: Lithopone has fine particles, loose structure, white color and good hiding power, so it has good applicability with other color pigments in the components of ink.
3. Rubber and plastic: Lithopone can whiten and improve the strength of products.
4. Building materials: It can not only be used as water-based paint for the interior walls of buildings, but also as a filler for plastic veneers such as wallpaper, floor paint, and tables.
