Lithopone is a white pigment made of zinc sulfide and barium sulfate. This combination of sulfide and sulfate creates a white product that acts as a matte or opacifier in a variety of products from paint to plastics. In its powder form, it is used to tint lacquers, varnishes, and enamels. It is often used in products to provide opacity for paints, plastics, paper and even ceramics. It is also used as an extender in paints, providing bulk, reducing cost, increasing coverage, and providing improved flow. The primary attribute of lithopone is its whiteness and opacity, which makes it suitable for many applications.
When used in paint, lithopone increases the opacity and whiteness of the finished product without affecting the hue. Its inherent opacity can be further enhanced by using specific grades of lithopone. In plastics, lithopone is used to make parts look brighter and more translucent. In paper, it is used to make paper look whiter and improves the printing properties of the paper. In ceramics, it is used to bring out the true color of glazes.
Lithopone is a highly versatile product, with a multitude of uses in a wide variety of industries. It has a long history of use, and it continues to be used in many industries today. Its robust properties make it an ideal choice for a number of applications.
