Pigment Orange 13

Pigment Orange 13 is orange pigment powder and most available types in the marketare semi-opaque type.  Its color shade is slightly yellower than pigment orange 34 but with lower coloring strength. Its fastness  in the application is also worse than Orange 34. It is suitable for the use in printing inks, but not the packaging inks, as its fastness is not so good. The solvent resistance in the ink is quite well, and the heat resistance of ink with PO13 can reach 200°C. It also has good performance in varnish and disinfection treatment, therefore, it is highly recommend to use in metal decoration printing inks.
