Pigment Blue 28 (named cobalt aluminium blue) is a bright color with reddish blue,which has a special anti-far-infrared function. it is also one kinds of environmental protection pigments, which is internationally recognized as non-toxic pigments. It is easy to disperse, with excellent heat resistance,weather resistance,acid & alkali resistance,and resist to a variety of solvents, good hiding power.
It is mainly used in high temperature (resistant) coatings, ceramics, enamels, glass coloring, coloring of high
temperature resistance engineering plastics,food contact plastics,as well as art paint.
