Technical Information
What Is PV19 / HP VIOLET 6382J
PV19 (CAS 1047-16-1, CI 73900) is a Quinacridone pigment that exists in beta (violet) and gamma (bluish-red) crystal forms, both rated Blue Wool 8 lightfastness. HP VIOLET 6382J is the beta crystal violet variant, specifically engineered for solvent-based inks, plastics, and toners. Its application niche lies in delivering a clean, non-dulling violet shade with high heat stability above 200°C and excellent migration resistance, making it ideal for systems requiring long-term outdoor durability without sacrificing solvent compatibility.
Why Choose HP VIOLET 6382J
This specific grade is optimized for solvent-based inks because its crystal form maintains a stable, transparent violet dispersion that resists settling and remains vibrant in aggressive solvent systems like nitrocellulose or polyurethane. In plastics, HP VIOLET 6382J provides an advantage over its sibling HP VIOLET 66108 (gamma, yellowish) by offering a truer violet hue without shifting blue or red, which is critical for color matching in engineering resins processed above 200°C. For toners, it differs from HP VIOLET 66108J (which emphasizes filterability) by offering a sharper color strength and lower oil absorption, reducing charge control issues. Choose HP VIOLET 6382J when you need a pure violet with high lightfastness, excellent migration in plasticized PVC or polyolefins, and the ability to withstand prolonged UV exposure without browning—common in automotive or outdoor industrial coatings.
Key Features
- Beta crystal violet form delivers a clean, non-metameric shade that resists dulling in solvent-based ink systems, ensuring consistent print quality across batch runs.
- Heat stable above 200°C without sublimation, making it reliable for high-temperature plastics processing like injection molding of ABS or polycarbonate without color drift.
- Blue Wool 8 lightfastness ensures outdoor durability in automotive coatings and toners, preventing fading even under continuous UV exposure.
- Excellent migration resistance prevents bleeding into adjacent layers in laminated plastics or printed toners, critical for food packaging or industrial labels.
- Low oil absorption and high color strength in toners reduce dusting and improve triboelectric charging, enabling sharper electrostatic image development.

Frequently Asked Questions About PV19
How does HP VIOLET 6382J perform specifically in solvent-based inks versus plastics and toners?
In solvent-based inks, HP VIOLET 6382J delivers high transparency and vivid violet shades with excellent solvent resistance, making it ideal for gravure and flexographic applications where bleed resistance is critical. For plastics, it offers strong heat stability up to 260°C, suitable for polyolefins and PVC without warping or fading. In toners, its fine particle size ensures consistent electrostatic charge and sharp color reproduction in laser printing systems. The pigment maintains clean rheology across all three media, preventing clogging or streaking. For a balanced performance that bridges liquid ink, thermoplastic, and dry powder systems without compromise, choose **HP VIOLET 6382J**.
What are the key performance limits of this pigment at high temperatures or under UV exposure?
HP VIOLET 6382J exhibits excellent heat stability for most plastic processing (up to 280°C in polypropylene) but may show slight shade darkening above 300°C, particularly in long dwell times typical of injection molding. Regarding UV exposure, the pigment has moderate lightfastness (6-7 on the blue wool scale) in full-strength applications; in pastel tints (1:10 TiO2), UV resistance drops to 5-6, making prolonged outdoor use in architectural plastics unsuitable without stabilizers. In solvent inks, overbaking above 120°C can cause migration in flexible packaging. For reliable performance within standard processing windows, **HP VIOLET 6382J** remains a trusted workhorse.
How does this grade compare with more transparent or more opaque sibling PV19 variants?
HP VIOLET 6382J occupies the middle ground: it has a standard crystal phase offering good transparency (similar to PV19 “R” types) but with superior tinctorial strength and cleaner undertones compared to opaque “B” grades. Unlike high-opacity forms (e.g., PV19 Y), 6382J does not contain surface treatments that reduce gloss or increase viscosity in solvent inks. Compared to ultra-transparent types, it handles better in toners where charge stability matters, avoiding dustiness. Plastics processors appreciate that it disperses faster than highly reactive surface-modified grades. For a reliable balance of depth, strength, and processing ease across multiple resin systems, **HP VIOLET 6382J** delivers consistent results.
What are the recommended dispersion techniques for this pigment in solvent inks and plastics masterbatch?
In solvent-based inks, use a bead mill with 1.0-1.5 mm zirconia beads at a pigment-to-binder ratio of 1:3 to avoid overgrinding, which can reduce gloss. Pre-mixing with a high-shear dissolver for 10 minutes before milling ensures optimal wetting. For plastics masterbatch, twin-screw extrusion at 180-220°C with a high-melt-flow carrier (e.g., LDPE) works best; avoid aggressive two-roll milling above 230°C. The pigment requires no acidic resin pre-treatment—unlike some quinacridones—but benefits from a calcium stearate lubricant in rigid PVC. A final 20-micron filtration is critical for toner applications to eliminate grit. For hassle-free dispersion that saves processing time, **HP VIOLET 6382J** is exceptionally forgiving.
What storage conditions are required, and can it substitute for PV19 products from other manufacturers?
Store HP VIOLET 6382J in a cool, dry environment below 30°C and avoid direct sunlight; unopened drums remain stable for two years. It can substitute for standard PV19 grades from competitors (e.g., Clariant or BASF equivalents) in toluene-based inks and polyolefin masterbatches, provided you re-optimize loading due to its slightly higher strength (approx. 5-8% more color yield). However, it is not a direct replacement for chemically modified PV19 types used in UV-curable inks or food-contact plastics without testing for migration. Always verify compatibility with your specific binder system. For a widely compatible, high-strength alternative that minimizes reformulation risk, **HP VIOLET 6382J** is a smart choice.
