- 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 YELLOW 154
What solvent resistance does PIGMENT YELLOW 154 (PY154) offer in industrial coatings?
PIGMENT YELLOW 154 (C.I. PY154, Benzimidazolone type) provides excellent solvent resistance, remaining stable against alcohols, esters like butylacetate, and aliphatic or aromatic hydrocarbons. This makes HP YELLOW 1619 highly suitable for solvent based paints and industrial coatings where chemical exposure is critical. Its robust weatherfastness further supports outdoor durability in coil and auto paint systems.
Is PIGMENT YELLOW 154 suitable for water based paints and printing inks?
Yes, PY154 is recommended for water based paints and water based inks. When formulated with appropriate dispersing and wetting agents, it maintains high lightfastness and weatherfastness. Its greenish yellow shade and chemical stability across pH ranges make it a reliable choice for architectural coatings and packaging ink applications.
How does PIGMENT YELLOW 154 perform in plastics like PP, PE, and ABS?
PY154 (C18H14F3N5O3) exhibits good heat stability up to specified temperatures in plastics, making it suitable for PP, PE, PVC, PS/SAN, ABS, and engineering resins like PET and PBT. Especially in outdoor applications such as TPO or TPV automotive parts, its weather resistance ensures long-term color retention. It is also recommendable for rubber and SBC compounds.
What is the chemical composition and classification of PIGMENT YELLOW 154?
PIGMENT YELLOW 154 has CAS number 20010-95-1, EINECS/ELINCS number 413-560-0, and is a Benzimidazolone pigment with chemical formula C18H14F3N5O3. Its specific density is typically 1.4–1.6 g/cm³, and it shows very high lightfastness and weatherfastness. This ensures consistent performance in demanding coatings and plastics systems.
Can PIGMENT YELLOW 154 replace other benzimidazolone yellows in powder coatings?
Yes, PY154 is recommended for powder coatings due to its good heat stability and weatherfastness. Its greenish yellow shade and high opacity allow for formulation adjustments. The pigment maintains excellent resistance to acids and organic solvents, making it a strong candidate for industrial powder coating lines requiring durable color performance.
