In the demanding fields of high-end UV-curable inkjet printing and UV flexographic printing, achieving efficient pigment dispersion, narrow nano-scale particle size distribution, and long-term storage stability is critical for jetting reliability, color saturation, and weatherability. Especially in challenging organic pigment systems such as azo yellows and reds, conventional dispersants often struggle with high millbase viscosities, flocculation, and settling during storage.

Engineered specifically for solvent-based and 100% solids UV-curable systems, Tianjin Ruikel Chemical Co., Ltd. introduces RD-9814, a 100% active polymeric super-dispersant that matches the exceptional performance of Lubrizol Solsperse J180. It significantly lowers millbase viscosity, maximizes pigment loading, and serves as the ideal choice for formulating high-performance UV inkjet and flexo printing inks.

1. RD-9814 Core Technical Specifications & Benchmark

RD-9814 contains a high concentration of active adsorbent groups, enabling powerful anchoring onto both organic and inorganic pigment surfaces to achieve outstanding steric hindrance stabilization.

2. Key Performance Advantages (Matching Lubrizol J180 Quality)

1. Ultra-Fine Nano Particle Size & High Tinting Strength

   Much like Solsperse J180, RD-9814 enables a narrow nano-scale particle size distribution, granting UV inkjet inks exceptional flow properties, high color saturation, and prevention of printhead nozzle clogging.

2. Superior Wetting & Dispersion for Yellow & Red Azo Pigments

   Specifically optimized for notoriously difficult organic yellow and red pigments, RD-9814 demonstrates unique affinity and de-flocculation efficiency, effortlessly producing stable, high-solid-content, low-viscosity millbases.

3. Significant Millbase Viscosity Reduction

   High active content means no redundant carriers are introduced into your formulation. It effectively reduces system viscosity under high pigment loading, boosting grinding efficiency and enabling higher solids content.

4. Exceptional Storage Stability

   Through powerful steric hindrance effects, it effectively prevents secondary agglomeration and crystal growth of pigment particles during long-term storage or temperature fluctuations.

3. Recommended Applications & Dosage

A. Primary Application Fields

• UV Nano-Pigment Pastes: Particularly suitable for organic yellow pigments, as well as red and blue systems.

• Advanced Digital Inks: UV inkjet printing inks.

• Packaging Printing Inks: UV flexographic (UV Flexo) inks and UV screen-printing inks.

B. Recommended Dosage

• Organic Pigments: 7% - 15% (by weight of total pigment).

• Inorganic Pigments: 0.5% - 2% (by weight of total pigment).

4. Usage Guidelines & Storage Instructions

• Mixing Procedure:

1. First, completely dissolve and mix RD-9814 into the grinding medium mixture (monomers/oligomers/solvent blend).

2. Slowly add the pigment in stages and proceed with standard grinding and dispersion equipment (such as bead mills or high-speed dissolvers).

• Packing: 25 KG or 200 KG plastic drums.

• Storage: Keep away from sources of fire and light; store tightly sealed in a dark, cool, and well-ventilated place.

5. Summary & Sample Requests
