Product characteristics: Meets halogen-free environmental requirements. Lightfastness is superior to traditional benzidine yellow series (e.g., 1-2 grades higher than Pigment Yellow 14). It exhibits good heat resistance and chemical resistance.
Lightfastness: Grade 5-6
Acid and alkali resistance: Both grade 5
Heat resistance: 200°C (Heat stability in HDPE at 1/3 standard depth can reach 280°C/5min)
Migration resistance: Grade 5 (No migration)
Weather resistance: Grade 5 (Suitable for long-term outdoor exposure, but decreases to grade 4 when diluted)
Acid resistance: Grade 5 (Excellent)
Alkali resistance: Grade 5 (Excellent), stable in pH range 6-8
Water resistance: Grade 4 (Good)
Oil resistance: Grade 5 (Excellent). Soluble in organic solvents such as butanol, with resistance to solvent bleeding.

Product applications:
A modified product of Pigment Yellow 13, featuring excellent tinting strength and transparency. Enhanced flow properties through specific surface treatment modifiers. Color meets CIE12-66 standard yellow. Mainly used in offset printing inks, water-based inks, plastics, and powder coatings. Particularly suitable for offset/UV inks, engineering plastics (e.g., HDPE, ABS), and automotive coatings.
