PRODUCT PROFILE
P.B.15:4Pigment Blue 15:4 — grade profile
Pigment Blue 15:4 (P.B.15:4) is a beta-form copper phthalocyanine pigment for Coatings & paint and Printing inks. Compare shade, tinting strength, dispersion and processing stability in the customer’s actual resin or binder rather than relying on one universal value.
Published screening data includes published heat reference 300 °C, light fastness 7/8 and oil absorption 50–60 ml/100g. Application-specific heat and fastness entries in the technical table take precedence.
Primary listed fits include Solvent-based decorative coatings and NC inks; Coil coatings, Offset inks and Water-based inks are listed for evaluation.
Selection focus
At equal loading, compare shade, tinting strength, dispersion and resin or binder compatibility, then confirm the required fastness under the final process conditions.
