The refractive index, represented by the letter n, of a material describes how light propagates through and is bent by, that material. The magnitude of the refractive index, depending upon the electronic structure of the molecules, governs to what extent the path of light changes, when entering or leaving a material.

Particles in a matrix, like pigment particles surrounded by the binder system in a coating, ink or plastic, can change the propagation direction of light when the particles and the matrix have a different refractive index. This phenomenon, called scattering, results in both white color (provided that the particles do not absorb visible light) and the hiding power of the coating.

Lithopone is a specialized white pigment that has been widely used in various applications, including paints, coatings, plastics, and paper industries. Known for its excellent whiteness and opacity, lithopone is predominantly composed of barium sulfate and zinc sulfide, making it an effective alternative to titanium dioxide for certain applications. As industries continue to evolve, understanding the wholesale lithopone pigment pricelist becomes essential for manufacturers and suppliers alike.
