C.I. Pigment Blue 29 - Physico-chemical Properties
| Molecular Formula | Al6Na8O24S3Si6 |
| Molar Mass | 994.500988 |
| Specific Gravity | 2.3 |
| Storage Condition | Room Temprature |
| Stability | Stable. Incompatible with strong oxidizing agents. |
| Sensitive | 1: no significant reaction with aqueous systems |
| Physical and Chemical Properties | non-toxic inorganic pigment, blue powder, bright and fresh in color, which is not comparable to other blue colors and even cannot be blended. Insoluble in water. It has the effect of eliminating and reducing the yellow color light contained in white paint or other white materials. Low color strength and hiding power, poor corrosion resistance. Alkali resistance, high temperature resistance, in the atmosphere of the sun and wind and rain is extremely stable. Have good hydrophilicity, but not acid, acid decomposition discoloration. |
| Use | inorganic blue pigment. The coating industry is used in the manufacture of color paints to make whiteness more distinct. The rubber industry is used to color, whiten or blend grass green with yellow pigment for rubber products such as shoe soles and rubber plates. The paper industry is used in pulp to produce pulp with a bright white or blue color. The printing and dyeing textile industry is used for white cotton and knitted fabrics to increase the whiteness of the fiber and the printing trademark of the knitted fabric of the cloth. The pigment industry is used for the coloring of oil paints and as a whitening agent for white pigments. The plastic industry is used for the coloring, erasing and whitening of plastic products and artificial leather. The construction industry is used for the coloring of cement square brick and artificial marble. In addition, Ultramarine can also be used for the antioxidant of perfluorocarbon resin, hydrogenation cracking catalyst, and the adsorption of uranium from seawater. |

C.I. Pigment Blue 29 - Safety
Open Data Verified Data
The product is non-toxic. Packed with iron drum lined with polyethylene plastic bag, each net weight 25kg, 50kg. Store in a ventilated, dry warehouse. Should pay attention to moisture. It should not be co-stored and mixed with acid articles. Hazards and protection: inhalation of dust, manifested as loss of appetite, hiccup gas containing hydrogen sulfide, decreased acidity of gastric juice. If swallowed into the stomach, there will be symptoms of hydrogen sulfide poisoning, lung pneumoconiosis-like changes. Ultramarine dust is harmful to human body, so it is necessary to wear an anti-virus mask when working, and the workshop should pay attention to ventilation and dust removal. After work to wash and change clothes, protective equipment should be stored separately, often Bath. Fire, water, sand and all kinds of fire extinguishing.
