PRODUCT PROFILE
P.Y.183Pigment Yellow 183 — grade profile
Pigment Yellow 183 (P.Y.183) is a monoazo lake pigment for Plastics & masterbatch, Coatings & paint and Textiles & fibers 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 300 °C and light fastness 7–8/8. Application-specific heat and fastness entries in the technical table take precedence.
Primary listed fits include PVC, Polyolefins (PO), Polystyrene (PS) and ABS; PP fiber, Powder coatings and PET fiber are listed for evaluation.
Selection focus
At equal loading and dispersion, compare full shade, tint, transparency or opacity, heat stability, migration and the intended exposure conditions.
