- 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
What factors determine the Weatherability of Pigment Red 254 in high-durability coatings?
Pigment Red 254 (CAS 84632-65-1) delivers outstanding weather resistance in exterior-grade coatings due to its DPP (diketopyrrolo-pyrrole) chemical structure, formulated as C18H10Cl2N2O2. This high-molecular-weight organic pigment offers exceptional lightfastness and thermal stability up to high temperatures, making it ideal for original automotive finishes and automotive refinishes. In solvent-based and water-based paint systems, PR254 resists fading and chalking even under prolonged UV exposure, supported by its dense crystal lattice with specific gravity optimized for coating dispersion. For industrial paints and powder coatings, the pigment maintains color integrity in both full-shade red and bluish-red white reductions, meeting rigorous OEM performance standards without requiring external stabilizers.
Can Pigment Red 254 be used in polyolefin plastics like PP and PE without migration issues?
Yes, Pigment Red 254 (C.I. PR 254, HP RED 2135) exhibits excellent bleeding fastness in polyolefins such as PP, PE, and TPO, preventing unwanted migration during processing or end-use. In plastic masterbatch applications for injection molding and extrusion, DPP chemistry ensures the pigment disperses uniformly within the polymer matrix, maintaining color strength from 180-300°C heat stability (depending on resin). For engineering plastics like ABS, POM, and PBT, PR254 provides reliable performance without surface blooming, even in thin-wall parts. This makes it suitable for automotive interior/exterior components and durable consumer goods.
How does Pigment Red 254 perform in offset printing inks regarding transparency and strength?
Pigment Red 254 demonstrates high tinctorial strength in offset inks, allowing reduced pigment load while maintaining vibrant red shades. In full-shade prints, the pigment yields a medium red hue, while white reductions produce a distinctly bluish red, enhancing color brilliance for packaging and commercial graphics. Its chemical stability (C18H10Cl2N2O2) supports resistance to common printing solvents and fountain solutions, ensuring clean dot reproduction and minimized plate contamination. For water-based and solvent-based ink systems, PR254 formulates effectively with proper dispersants, achieving consistent rheology essential for high-speed press runs.
What differentiates Pigment Red 254 from other red organic pigments for industrial coil coatings?
Pigment Red 254 (DPP type, CI 56110) offers a unique balance of chroma and durability specifically suited for coil coatings that undergo post-forming and severe weathering. Compared to azo reds, its larger molecular structure provides superior heat stability (resistive to 200°C+ substrate temperatures during baking) and outstanding acid/alkali resistance critical for metal substrates. The pigment’s specific density and particle size distribution enable consistent color development in thin film applications for building panels and appliances. As a globally compliant colorant (EINECS listed), PR254 meets VOC regulations for both solvent-based and water-based coil coating lines without sacrificing gloss retention.
How is batch consistency maintained for Pigment Red 254 across multi-year production cycles?
Honor Pigments ensures batch-to-batch consistency for Pigment Red 254 (HP RED 2135) through ISO 9001 protocols that test every lot for color strength, shade deviation, dispersibility, and particle size distribution. Each production run references internal master standards, with spectrophotometric verification against delta-E tolerances ⩽ 0.5. The DPP synthesis process (C18H10Cl2N2O2) is controlled to minimize chlorinated by-products, yielding a pure pigment that exhibits stable performance in recommended binders for coatings, plastics, and printing inks. All test results accompany shipments, enabling processors to maintain repeatable formulations without re-qualification.
