Purple Pigment for Water-Based Ink Paste and Coating RL VT2300W - High Color Strength for Paint and Ink

Purple Pigment RL VT2300W is a next-generation organic pigment engineered to deliver intense color strength, exceptional stability, and unparalleled compatibility in water-based systems. Designed for environmentally conscious formulations, this pigment combines vibrant chromatic performance with low-VOC compliance, making it ideal for premium inks, architectural coatings, and specialty packaging. Whether creating bold graphics on flexible films or durable finishes on industrial equipment, RL VT2300W ensures consistent color fidelity across demanding applications while meeting global sustainability standards.

‌Core Technical Attributes‌

‌1. Superior Color Strength‌
With a tinting power ‌40% higher‌ than conventional violet pigments, RL VT2300W achieves full chromatic saturation at ‌1.0–1.8% loading‌ in water-based systems. Its optimized particle morphology (D50: 0.1–0.3 μm) maximizes light absorption, delivering a deep purple hue with CIELAB coordinates ‌L = 32, a = 45, b* = -25**‌ for unmatched vibrancy.

‌2. Water-Based Compatibility‌
Specially modified surface chemistry ensures rapid dispersion in aqueous formulations (<5 minutes at 1,500 rpm). Achieves Hegman grind values of ‌7.5+‌ without milling aids, eliminating speckling in high-speed inkjet and flexographic printing processes.

‌3. Lightfastness & Weather Resistance‌
Rated ‌Grade 7–8‌ on the Blue Wool Scale (ISO 105-B02), the pigment withstands ‌2,000+ hours‌ of QUV-A exposure (ASTM G154) with ΔE <1.5, ensuring fade resistance in outdoor signage, automotive wraps, and architectural cladding.

‌4. Chemical and Thermal Resilience‌

• Stable in pH ranges from ‌4–11‌ (ASTM D1308)
• Resists plasticizer migration in PVC films (≤0.2% weight loss at 70°C, ISO 177)
• Maintains color integrity at processing temperatures up to ‌220°C‌ (428°F) for powder coatings and heat-set inks

• ‌Universal Compatibility‌: Stable in acrylic, polyurethane, and styrene-acrylate binders
• ‌Metamerism Control‌: Matches Pantone 2685C and RAL 4008 across substrates
• ‌Opacity Flexibility‌: Achieves transparent glazes (0.5% loading) or full coverage (2.5%)

‌Recommended Usage‌:

• ‌Inks‌: 8–15% in pigment concentrates for water-based systems
• ‌Coatings‌: 1.2–2.5% by weight in architectural emulsions
• ‌Masterbatches‌: 20–30% in PLA or PETG carriers for bioplastics

‌Processing Efficiency‌

• ‌Dispersion‌: Pre-dispersed forms available for "dump-and-stir" incorporation
• ‌Drying Speed‌: Enables 25% faster line speeds in web offset printing vs. traditional pigments
• ‌Storage Stability‌: 12-month shelf life in sealed containers; viscosity drift <5% at 40°C
