PRODUCT PROFILE
P.R.52:1Pigment Red 52:1 — grade profile
Pigment Red 52:1 (P.R.52:1) is a monoazo calcium-lake 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 180 °C, light fastness 6/8 and oil absorption 45–55 ml/100g. Application-specific heat and fastness entries in the technical table take precedence.
The listed application scope is Coatings & paint.
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.
