PRODUCT PROFILE
P.Y.151Pigment Yellow 151 — grade profile
Pigment Yellow 151 (P.Y.151) is a benzimidazolone pigment for Coatings & paint, Printing inks and Plastics & masterbatch 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 200 °C and light fastness 8/8. Application-specific heat and fastness entries in the technical table take precedence.
Primary listed fits include General coatings screening and General printing-ink screening; General plastics screening 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.
