What matters most with Pigment Violet 19 beta

Pigment Violet 19 beta (PV19 β) is a quinacridone blue‑shade violet favored for high chroma and a robust fastness profile across inks, coatings, and plastics. For inkjet specifically, three properties dominate outcomes:

• Narrow particle size distribution with D90 typically ≤ 250 nm for reliable jetting

• Low viscosity at target pigment solids for stable drop formation

• Excellent filterability through 0.2–1.0 μm media without residue buildup

Across coatings, PV19 β is known for excellent lightfastness in full shade and very strong weathering, while in plastics it offers high tint strength and good heat stability in polyolefins and engineering resins. These category expectations are echoed in authoritative directories from Vibrantz and DCL. For example, PV19 commonly reaches Blue Wool 7–8 in masstone and maintains color well in accelerated weathering, with plastics stability reported near the 280–300 °C window depending on resin and dwell time, as summarized in the DCL plastics methodology and brand brochures. See the portfolio context in the Vibrantz organic pigments overview and DCL directories for standard testing conventions and performance ranges.

• HP Violet 6382J appears across Honor’s portfolio as an inkjet‑friendly PV19 variant. Product page: HP Violet 6382J.

According to the Vibrantz and DCL materials, PV19 is widely deployed across inks, coatings, and plastics due to its balance of high chroma and resistance. See the Vibrantz organic pigments landing for portfolio‑level positioning and the DCL directories for application test conventions and typical ranges.

Testing protocol and thresholds we use

To evaluate whether a PV19 β grade is truly inkjet‑ready while still meeting coatings and plastics expectations, we use the following framework:

• Inkjet dispersion integrity: Dynamic light scattering for D50/D90; 0.2 μm PTFE filter pass time for 100 mL; Brookfield viscosity at 25 °C across practical solids; 30‑minute runtime on a standard piezo head using fine patterns and solid fills

• Coatings durability: Acrylate panel drawdowns at comparable PVC; QUV‑A exposure with ΔE at 250 and 500 hours; Blue Wool strips for context

• Plastics processing: PP and ABS plaques processed at 280–300 °C; ΔE after 10 minutes at temperature; migration rating on HDPE; visual assessment of plate‑out

Success thresholds used by many labs and referenced in supplier literature include D90 ≤ 250 nm for inkjet dispersions, viscosity in the 2–4 mPa·s window at printing solids for aqueous systems, ΔE ≤ 2 after 250 hours QUV on coatings test panels, and ΔE under ~2.0 after a 10‑minute 280–300 °C plastics dwell—depending on resin and stabilizers. When quantitative internal results are available, they should be reported with instrument settings and sample prep. Where such data is not public, treat the above as targets to validate during sampling.

Pigment Violet 19 beta for inkjet formulations

The hero benefit for PV19 in inkjet is the ability to mill dispersions to a narrow, stable PSD that stays below a nozzle’s effective aperture and resists agglomeration under shear and storage. In practice, that means targeting D50 near 80–150 nm and keeping the D90 well under 250 nm while preserving a low‑viscosity window so the ink jettability isn’t compromised.

Honor Pigments lists HP Violet 66108J specifically for water‑based inkjet with excellent filter properties, suggesting attention to PSD discipline and low residue. See Honor’s Inkjet Inks category for positioning. The company also offers HP Violet 6382J, which appears as an inkjet‑friendly PV19 grade suitable for similar workflows: HP Violet 6382J.

An anonymized case from a desktop photo inkjet program illustrates what good looks like. The formulator ran a standard piezo head for 30 minutes continuously with a PV19 β magenta‑violet dispersion. The ink retained a low, stable viscosity at room temperature, passed a 0.2 μm filter without observable residue accumulation, and produced fine text and barcode patterns with minimal missing nozzles. While exact PSD values are not published here, the filterability behavior and nozzle reliability align with a narrow PSD dispersion and a well‑chosen dispersant package. If you’re qualifying a PV19 β for inkjet, think of it this way: if filtration is slow or residue builds up, your PSD tail is likely too fat—tighten the milling curve and revisit dispersant chemistry.

Practical tips for aqueous inkjet dispersions

• Use sodium polyacrylate or polyurethane dispersants with a pH near neutral and control ionic strength to limit flocculation

• Map viscosity versus solids; find the lowest workable solids that still meet color targets to keep jetting stable

Pigment Violet 19 beta in industrial coatings

PV19 β’s reputation in coatings is built on durability. Honor Pigments’ HP Violet 6362 is positioned as a β‑type PV19 for coatings with strong light, weather, and heat stability: HP Violet 6362. In typical acrylic or polyurethane systems, PV19 shows Blue Wool 7–8 in masstone and holds color through accelerated weathering at QUV‑A checkpoints when properly dispersed and stabilized. DCL’s coatings brochures outline common test setups and interpretation of ΔE changes over time, which you can use to set acceptance criteria for exterior‑exposed parts.

In the lab, we look for a smooth film with high gloss retention after 250 hours QUV and minimal ΔE drift in both masstone and a standard white reduction. If your panels show early chalking or faster ΔE change in tint, revisit pigment volume concentration, consider UV absorbers, and check for over‑grinding that might have increased surface area without adequate stabilization.

Pigment Violet 19 beta for plastics and masterbatch

In polyolefins and engineering resins, PV19 β typically delivers strong tinting strength and a clean bluish violet shade with respectable heat stability. Third‑party references indicate viability up to roughly 280–300 °C with careful compounding and short dwell times. Sudarshan’s PV Fast Red E5B, a β‑type PV19 used as a plastics reference point, reports suitability in this processing window, offering a practical benchmark for PP and ABS color concentrates.

When compounding PV19 β:

• Confirm ΔE after a realistic dwell at target temperature in your specific resin system

• Check migration resistance and plate‑out at the intended letdown level and processing conditions

If you’re running PC, PET, or high‑heat nylons, perform extended dwell tests and adjust stabilizers as needed to keep hue shift under control.
