PRODUCT PROFILE
P.R.170Pigment Red 170 F5RK — grade profile
Pigment Red 170 F5RK (P.R.170) is a naphthol as pigment for Plastics & masterbatch, 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 220 °C, light fastness 7–8/8 and oil absorption 35–45 ml/100g. Application-specific heat and fastness entries in the technical table take precedence.
Primary listed fits include PVC, Polyolefins (PO), Industrial coatings, Coil coatings, Powder coatings and OEM coatings; Water-based decorative coatings, Solvent-based decorative coatings, Pigment textile printing and Offset 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.
