PIGMENT YELLOW 110/ HP YELLOW 1315

What Is PY110 / HP YELLOW 1315

CAS 5590-18-1, CI 56280, Type Isoindolinone. This specific grade is a high-performance greenish-yellow organic pigment with Blue Wool lightfastness ratings of 7-8. HP YELLOW 1315 is engineered primarily for demanding applications in printing inks, industrial coatings, and plastics where superior weather resistance and migration stability are required. Unlike standard yellow pigments, this grade maintains color integrity under prolonged UV exposure and high-temperature processing.

Why Choose HP YELLOW 1315

Choose HP YELLOW 1315 for its distinct greenish shade that provides clean, bright yellow tones in printing inks, coil coatings, and automotive plastics. Unlike its sibling HP YELLOW 1346 (which offers a reddish undertone), this grade delivers the cooler yellow end of the CI 56280 spectrum. In printing inks, it produces vibrant offset and gravure prints with excellent transparency. For coatings, its superior weather resistance outperforms benzimidazolone yellows, making it ideal for exterior applications like automotive topcoats and architectural paints. In plastics, it withstands injection molding temperatures without shifting color or bleeding. Select this specific grade when you need a greenish-yellow that resists fading in outdoor use, requires low migration in food-contact packaging, or demands consistent performance in high-heat processing cycles.

Key Features

• Blue Wool lightfastness rating 7-8 ensures color retention in exterior printing inks and automotive coatings exposed to continuous sunlight.
• Superior heat stability up to 280°C allows trouble-free processing in injection-molded polyolefin plastics without shade shift.
• Excellent migration resistance prevents bleeding in plasticized PVC and prevents ink transfer in layered packaging applications.
• High weather resistance outperforms benzimidazolone yellows, making it the cost-effective choice for long-life coil and architectural coatings.
• Clean greenish-yellow hue provides high chromatic strength for high-gloss printing inks and transparent effect layers in automotive paint systems.

Frequently Asked Questions About PY110

How does HP YELLOW 1315 perform specifically in solvent-based versus water-based printing inks?

HP YELLOW 1315 (Pigment Yellow 110) is an isoindolinone pigment optimized for solvent-based gravure and flexo inks due to its excellent solvent resistance and low migration in toluene/acetone systems. In water-based inks, it requires tailored wetting agents because its hydrophobic surface can cause flocculation. It offers high transparency in overprint lacquers but may struggle with opacity in one-pass coatings unless combined with TiO₂. For waterborne systems, we recommend using a pre-dispersed presscake grade to avoid grit. The pigment excels in industrial paints where chemical resistance is critical but less ideal for high-gloss aqueous inks without resin optimization. Takeaway: HP YELLOW 1315 is a reliable workhorse for solvent systems, but waterborne formulators must invest in dispersion additives to unlock its full potential.

What are the main performance limits of PY110 in outdoor coatings and engineering plastics?

PY110 (HP YELLOW 1315) offers outstanding lightfastness (7–8 on the blue wool scale) and heat stability up to 280°C, making it suitable for polycarbonate and ABS. However, its Achilles’ heel is severe warpage in HDPE/LDPE due to anisotropic crystal growth, causing dimensional distortion in injection-molded parts. In coil coatings, it passes 5-year Florida exposure but fades noticeably with high humidity (chalking grade 3–4), unlike its quinacridone rivals. For PVC, plasticizer migration can dull the shade over time. In nylon, the pigment catalyzes polymer degradation above 290°C, limiting residence time. Always test for stress cracking in thick sections. Takeaway: HP YELLOW 1315 is a premium choice for UV-stable rigid plastics but demands pre-screening for warpage and thermal runaway in specific engineering resins.

How does HP YELLOW 1315 compare with PY110 alternatives like PY191 or PY139 in cost vs. performance?

Compared to PY191 (azo yellow), HP YELLOW 1315 costs 2–3x more but delivers vastly superior migration resistance (suitable for food contact) and heat stability (>260°C vs. 200°C). Versus PY139 (isoindoline), PY110 has higher chroma (brighter green-shade yellow) but slightly lower opacity, requiring 15% more pigment for full hiding in coatings. In plastics, PY139 offers better flow (lower viscosity) at high loadings, while PY110 excels in weatherability. The price premium is justified for exterior automotive coatings or medical devices but not for disposable toys. For printing inks, PY191 is 60% cheaper but fails FDA clearances. Always compare CI 56280 against your substrate’s temperature curve. Takeaway: HP YELLOW 1315 is the cost-effective specialist for demanding end-uses where inferior yellows fail prematurely.

What are the critical dispersion techniques required for HP YELLOW 1315 in industrial coatings?

HP YELLOW 1315 has a high surface energy (40–45 mJ/m²) and tends to form hard aggregates under high shear. For millbase preparation, use a two-step method: pre-wet in a solvent/resin blend at low speed (500 rpm), then bead mill with 1.0–1.5 mm zirconia beads at 2000–2500 fpm. Avoid over-grinding beyond 30 minutes as this fractures crystals, reducing color strength. For solvent-free systems, add 0.5% hyperdispersant (Solsperse 5000 or equivalent) to stabilize. In NR/EPDM rubber, use a masterbatch in EPDM carrier to prevent dusting. Never use acidic resins (e.g., rosin esters) as they quench chroma. Final grind should achieve <10 micron particle size for optimal gloss. Takeaway: HP YELLOW 1315 rewards careful dispersion planning—poor grinding leads to speckled coatings and up to 20% loss of color value.

What storage conditions and substitution warnings apply to HP YELLOW 1315?

Store HP YELLOW 1315 in a dry environment below 40°C (104°F), as moisture absorption above 2% causes caking and reduced free-flow. In humid climates, use vacuum-sealed liners inside fiber drums—exposed pigment may form hard lumps requiring re-milling. Note: PY110 is not a drop-in replacement for PY53 (nickel-based) or PY83 (diarylide) because its green-shade tint differs by 4–5 ΔE units under D65 light. For color matching, expect +10% opacity in offset inks but -5% in gravure. Always requalify batches if substituting for CF118 (PY174) as rheology changes. Shelf life is 5 years from production date if sealed; after opening, use within 12 months. Test for chromatic shift in polyolefins after 6-month storage. Takeaway: HP YELLOW 1315 demands climate-controlled storage and careful pre-qualification before replacing any existing yellow pigment in your formulation.
