PRODUCT PROFILE
P.Y.81Pigment Yellow 81 — grade profile
Pigment Yellow 81 (P.Y.81) is a diarylide disazo pigment for Plastics & masterbatch, 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 200 °C, light fastness 6–7/8, oil absorption 35–45 g/100g and migration resistance 4/5. Application-specific heat and fastness entries in the technical table take precedence.
Primary listed fits include PVC, Polyolefins (PO), Industrial coatings, Powder coatings, Pigment textile printing and Offset inks.
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.
