P . B. 28 Cobalt Aluminate Blue Spinel 1. Product Information: Color Index : P.B.28 (77346) Chemical Name : Cobalt Aluminate Blue Spinel Chemical Character :Co/Al Oxide CAS Number: 1345-16-0 Physical Form: Blue powder Crystal Pattern : Spinel Pattern 2. Certificate : EU RoHS , EN71 , US FDA 3. Product Characteristics: A rich blue powder produced by high temperature calcination. This pigment has good UV and visible opacity, is chemically inert, heat resistant, and stable to ultraviolet light. It is non-bleeding and non-migratory. It has exceptional durability and hiding power, and is generally used in applications where resistance to heat, light, and weather are needed. It is compatible with most resin systems and polymers, and is non-warping. This product is very easily dispersible, does not need grinding for dispersion and can simply be stirred in using most laboratory and production equipment to achieve full dispersion 4. Advantages: High-temperature resistance High light fastness resistance Acid resistance Alkali resistance Weather resistance Easy to disperse Non-migration Non-bleeding 5.
