- Light fastness: Light fastness rating is assessed on 1 to 8 Blue Wool scale where 1 = ‘Poor’ and 8 = ‘Excellent’.
- Heat Stability: Heat stability values given indicate the maximum temperature at which the pigment can be stoved for 10 min. on the full shade and in reductions without undergoing any significant change in shade.
- Oil absorption: The oil absorption is determined on the basis of EN ISO 787-5 and given in g linseed oil per 100 gm. pigment.
- Solvent bleeding: The bleeding in solvents is tested using the powder grades and the visual rating given on 1 to 5 Grey scale
where 1 = ‘Heavy bleeding’ and 5 = ‘No bleeding”

Frequently Asked Questions — PIGMENT RED 254
How does PIGMENT RED 254 behave in high-temperature coil coating applications compared to other red organic pigments?
PIGMENT RED 254 (C.I. Constitution No. 74160, CAS: 84632-65-7) delivers medium-shade reds with a bluish undertone in white reductions. In coil coatings, its heat stability up to 200 °C and low viscosity profile ensure consistent film formation during oven curing. The covering powder form prevents settling in high-shear dispersion, maintaining color strength across batch runs.
What is the specific density of PIGMENT RED 254 and how does it affect dispersion in solvent-based paint formulations?
PIGMENT RED 254 has a specific density of 1.65 g/cm³ (ASTM D153). This density value, combined with its low-viscosity characteristic, allows efficient wetting in solvent-based systems (e.g., xylene/butanol blends). The particle size distribution (D50 ≈ 0.2 µm) minimizes flocculation in industrial paints, enabling 1:1 tint strength replacement for high-performance reds in automotive OEM coatings.
Is PIGMENT RED 254 compatible with polypropylene (PP) and ABS for outdoor plastic masterbatch?
Yes. PIGMENT RED 254 (C18H10Cl2N2O2) is recommended for PP, ABS, and PS/SAN masterbatch. Its weather resistance rating (ΔE < 1.5 after 500 h QUV) and heat stability up to 240 °C for 5 min make it suitable for outdoor plastics. In PP injection molding at 230 °C, color shift remains below 0.3 ΔE, confirming migration fastness per ISO 183-2014.
Why does PIGMENT RED 254 show superior bleeding fastness in water-based printing inks compared to PR170?
PIGMENT RED 254 (EINECS: 617-429-6) exhibits bleeding fastness ≥5 (1–5 scale) in water-based offset inks per ISO 2836. Its chemical structure—a diketo-pyrrolo-pyrrole (DPP) chromophore with two chlorine substituents—creates strong intermolecular hydrogen bonding, reducing solubility in water-glycol vehicles. This yields <2 % mass loss after 24 h submersion, versus 8–12 % for PR170.
How can I maintain batch-to-batch color consistency for PIGMENT RED 254 in powder coatings without laboratory rework?
Honor Pigments delivers PIGMENT RED 254 with ΔE < 0.5 (CIELAB D65/10°) across batches, verified by X-Rite spectrophotometry. Each 25 kg lot includes a Certificate of Analysis (COA) with tint strength (±2 %), dispersibility (≤10 µm Hegman gauge), and particle size D90 (≤1.5 µm). In epoxy-polyester powder coatings, this eliminates pre-blend shade adjustment, reducing scrap by 12 % per production run.
