PRODUCT PROFILE
P.R.188Pigment Red 188 — grade profile
Pigment Red 188 (P.R.188) is a organic 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 200 °C and light fastness 7/8. Application-specific heat and fastness entries in the technical table take precedence.
Primary listed fits include General plastics screening, General coatings screening and General printing-ink screening.
Selection focus
At equal loading and dispersion, compare full shade, tint, transparency or opacity, heat stability, migration and the intended exposure conditions.
