PRODUCT PROFILE
P.R.177Pigment Red 177 — grade profile
Pigment Red 177 (P.R.177) is a anthraquinone-family pigment for Plastics & masterbatch and Coatings & paint where processing stability and durability are defined selection criteria. Evaluate the grade in the intended resin or binder at the target loading and process conditions; every value below retains its published source and application context.
Published screening data includes published heat reference 280 °C and light fastness 8/8. Application-specific heat and fastness entries in the technical table take precedence.
Primary listed fits include PVC, Polyolefins (PO), Polystyrene (PS), PET, ABS and General coatings screening.
Selection focus
At equal loading and dispersion, compare full shade, tint, transparency or opacity, heat stability, migration and the intended exposure conditions.
