PRODUCT PROFILE
P.R.2Pigment Red 2 — grade profile
Pigment Red 2 (P.R.2) is a naphthol as pigment for Coatings & paint, Printing inks and Textiles & fibers. 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 150 °C, light fastness 6/8 and oil absorption 40–50 ml/100g. Application-specific heat and fastness entries in the technical table take precedence.
Primary listed fits include Pigment textile printing and Water-based inks; Water-based decorative coatings and UV 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.
