Ranbar Blue P5020 is a stable α-phthalocyanine blue pigment, pigment blue 15:2, belongs to the anti-flocculation α-type formulation, mainly used for paint coloring, especially when the pigment blue 15:1 shows obvious flocculation.

 

The improvement of CuPc phthalocyanine blue anti-flocculation performance is mainly through chemical modification (change the size and distribution of particle size can affect the performance), other application performance is similar to P.B.15:1, can be used in special gravure solvent printing ink ink.

 

This type of product, like other α-phthalocyanine blues, presents a stronger red light than the blue required for four-color printing inks.
