PRODUCT PROFILE
P.R.13Pigment Red 13 — grade profile
Pigment Red 13 (P.R.13) is a monoazo pigment for 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 150 °C, light fastness 5/8 and oil absorption 40–50 ml/100g. Application-specific heat and fastness entries in the technical table take precedence.
Primary listed fits include Industrial coatings; 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.
