Pigment Violet 23 (PV23): Specs and Buyer Guide for HP Violet 6172

Pigment Violet 23 (PV23): Complete Specs and Buyer Guide for HP Violet 6172

If you’re sourcing Pigment Violet 23 (PV23) for inks, coatings, or plastics, the real work isn’t finding “a PV23″—it’s qualifying a dioxazine violet pigment grade that can hold shade, strength, and processing stability in your system, backed by a clean SDS/TDS/COA package. Whether you’re a German automotive coatings formulator, a Japanese ink manufacturer, or a Brazilian masterbatch producer, PV23 qualification follows the same discipline: verify in your system, document the results, and control batch-to-batch consistency. This guide covers everything you need to evaluate HP Violet 6172 (PV23).

What is Pigment Violet 23 (PV23)?

Pigment Violet 23 is a dioxazine violet pigment widely used where high color strength and strong fastness are required. Key identifiers include Pigment Violet 23 CAS 6358-30-1, C.I. Constitution No. 51319, and chemical formula C34H22Cl2N4O2. For procurement and QC documentation, aligning on exact identifiers (C.I. name/number, CAS, and grade name) is the first step to avoiding mismatched approvals.

HP Violet 6172 Technical Specifications at a Glance

Where HP Violet 6172 Fits: Inks, Coatings, and Plastics

Honor Pigments lists HP Violet 6172 as recommended for water-based inks, water-based coatings, and industrial paints, with broader compatibility across solvent-/water-based coatings and multiple polymers. For a broader view of pigment options across these segments, see our complete organic pigments catalog.

PV23 for Water-Based Inks

Water-based systems put extra pressure on dispersion quality and stability. Buyers qualifying pigment violet 23 for water-based inks often validate:

• Dispersion stability (settling/flocculation risk under storage and shear)

• Color development at target let-down ratios

• Rub / abrasion resistance in the intended binder system

Browse our pigments for water-based inks category for complementary violet options. For Korean packaging ink producers and Southeast Asian flexo printers, PV23’s fastness profile is a key differentiator.

PV23 for Coatings and Industrial Paints

When evaluating pigment violet 23 for coatings, buyers typically focus on:

• Shade control (masstone and tint) across batches

• Gloss and flow impact (system-dependent)

• Weathering and light exposure performance aligned to the end-use

Explore our pigments for coatings catalog for related high-performance options.

PV23 for Plastics (including PVC)

When evaluating pigment violet 23 for plastics, teams usually look at:

• Heat history tolerance at your real processing profile (temperature and residence time)

• Migration/bleed risk in the finished article (especially in plasticized systems)

• Color drift after processing and aging

HP Violet 6172 lists heat stability 280°C/10 min and a PVC migration resistance rating of 5. Explore more pigments for plastics to compare PV23 with other high-performance violet grades.

PV23 Qualification Checklist: Procurement + Technical

Even with published technical data, qualification is where risks are reduced—especially when switching suppliers or approving a second source.

1) Grade identity and traceability

• C.I. name: Pigment Violet 23 (PV23); CAS: 6358-30-1

• Grade name: HP Violet 6172

• Batch/lot ID and manufacturing traceability fields on COA

2) Color consistency and strength control

• Masstone and tint comparison vs. an approved reference

• Tint strength tracking (with a consistent let-down method)

• Batch-to-batch delta monitoring in your color space method

3) Dispersion behavior in your system

• Time to reach target fineness (Hegman gauge per ASTM D1210)

• Viscosity impact at target pigment loading

• Stability after storage (hot/cold cycles if relevant)

4) Heat and chemical resistance alignment

• Heat stability: 280°C (10 min); Acid resistance: 5; Alkali resistance: 5

5) Migration / bleed risk (especially in PVC)

HP Violet 6172 lists a migration resistance in PVC rating of 5 on the product page.

⚠️ Warning: Final suitability depends on the complete formulation (polymer, plasticizers, additives, and processing). Always validate migration and stability in the finished system before approval.

Packaging, Storage, and Global Supply

HP Violet 6172 is supplied as powder with 25 kg/bag packaging and 400 kg per pallet guidance, with a stated 5-year shelf life. For buyers in Japan, Korea, Germany, and Southeast Asian markets, documentation turnaround and Incoterm flexibility are often as critical as the pigment’s technical performance.
