Dyes and Pigments

Pigment blue 29, also known as ultramarine blue, is a multi-component inorganic pigment (sulfur-containing sodium aluminosilicate), also known as cloud blue or ocean blue. Ultramarine is insoluble in water and is resistant to alkali, weather resistance and light resistance. However, it changes color when exposed to acid and has weak tinting and hiding power. Pigment blue 29 has a wide range of uses and is commonly used in coatings, plastics, resins, inks, construction, paper, detergents, painting pigments, cosmetics and other industries.
