Leukovärvid

Leukovärvid, also known as white pigments, are a category of inorganic substances primarily used to impart whiteness and opacity to various materials. They function by scattering visible light, which prevents light from passing through and makes the material appear white. The most common and widely used leukovärvid is titanium dioxide (TiO2), prized for its high refractive index, excellent hiding power, and UV-blocking properties. Other leukovärvid include zinc oxide (ZnO) and lithopone, a mixture of zinc sulfide and barium sulfate.

The applications of leukovärvid are extensive and span across numerous industries. In the paint and coatings industry, they are crucial for achieving bright, opaque finishes on walls, furniture, and vehicles. The plastics industry relies heavily on leukovärvid to color and opacify a vast array of plastic products, from packaging to consumer goods. The paper industry uses them to enhance the brightness and printability of paper and cardboard. Furthermore, leukovärvid find use in cosmetics, ceramics, textiles, and even food products as food additives for whitening purposes. The choice of leukovärvid depends on the specific application, desired properties such as durability and chemical resistance, and cost considerations.
