PRODUCT PROFILE
P.R.48:3Pigment Red 48:3 — grade profile
Pigment Red 48:3 (P.R.48:3) is a monoazo strontium-lake pigment for Plastics & masterbatch, Printing inks and Coatings & paint. 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 260 °C, light fastness 6/8 and oil absorption 45–55 ml/100g. Application-specific heat and fastness entries in the technical table take precedence.
Primary listed fits include PVC, Polyolefins (PO), Polystyrene (PS), PP fiber, Offset inks and Water-based inks; PA inks, Industrial coatings and Powder coatings 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.
