PRODUCT PROFILE
P.Y.138Pigment Yellow 138 — grade profile
Pigment Yellow 138 (P.Y.138) is a quinophthalone pigment for Plastics & masterbatch, Coatings & paint and Printing inks 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 6–7/8. Application-specific heat and fastness entries in the technical table take precedence.
Primary listed fits include PVC, Polyolefins (PO), Polystyrene (PS), General coatings screening and General printing-ink screening; ABS 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.
