PRODUCT PROFILE
P.Y.73Pigment Yellow 73 — grade profile
Pigment Yellow 73 (P.Y.73) is a monoazo arylide pigment for Coatings & paint 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 160 °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 Water-based decorative coatings and Pigment textile printing; Industrial 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.
