Ultramarine blue pigment is the oldest and the mostbright blue inorganic pigment, non-toxic, environmentally friendly, belongs to the category of inorganic pigment. It is used to enhance the chromaticity of white pigments or paints, can eliminate the yellow light in white paint or other white material, insoluble in water, light resistance, alkali resistance, heat resistance, in the atmosphere to the sun and wind and rain erosion is extremely stable, but not acid resistance, acid decomposition discoloration.

1. COLORING
Used for plastic, paint, rubber, printing and dyeing, ink, oil painting, color painting, and building exterior walls.
2. IMPROVE WHITENESS
Ultramarine can eliminate yellow light in white products or other white pigments. Used in papermaking, knittingindustry, detergent, clothing and footwear materials, white products, ete.
3. SPECIA FOR PAINTING
Using ultramarine powder to addblending oil, glue and propylene to make into oil painting, watercolor painting, gouache painting and acrylic painting pigments. Ultramarine is a mineral pignent featured with transparent apperance, weak hiding power and bright brightness, thus not suitable for painting very dark tones, but suitable for decorative colors, especially in the common use of ancient Chinese architecture.
4. COLOR MIXING
Adding ultramarine to black and gray can make the color have a soft luster.
5. OTHER APPLICATIONS
Used for plastic PVC-R/PVC-P/PVC/PP/PE/ABS/PC/PMMA/POM/PA/PET or PP spinning, etc. Ulltramarine can be used as antioxidant of perftuorinated carbon resin, hydrogenation pyrolysis catalyst, adsorption of uranium from seawater and so on.
