In the rapidly advancing digital printing industry, water-based inkjet inks demand the highest levels of pigment purity, particle size stability, and substrate compatibility. Pigment Red 170 (C.I. PR170), specifically the Pigment Red SY-238/239 series from Senova Chem, has emerged as a superior naphthol red for these high-precision applications. However, achieving professional-grade results requires a synergistic approach using advanced additives to manage the delicate balance of a water-based system.
1. Intense Color Brilliance and Bluish-Red Hue
Pigment Red 170 is renowned for its vibrant, bluish-red shade and excellent tinting strength. In inkjet applications, where the ink layer is extremely thin, Pigment Red SY-238 provides the necessary optical density to create sharp, vivid images. Its high color saturation ensures that digital prints remain striking and professional, meeting the rigorous aesthetic standards of premium packaging and textile printing.
2. Unmatched Stability with RD-9152 Inkjet Specialist
The most critical challenge in inkjet ink formulation is preventing nozzle clogging. This requires a dispersant that can maintain an ultra-fine particle size distribution over time. According to our 2025 Product Specification, we recommend RD-9152.
- Specialized Design: RD-9152 is specifically developed for water-based inkjet systems.
- Technical Edge: It offers excellent stability for organic pigments, ensuring that the Pigment Red 170 particles do not re-agglomerate even under the high-frequency thermal or piezo pressures of a printhead.
3. High-Performance Dispersion with RD-99031 and RD-9681
For large-batch water-based ink production or pigment concentrates, manufacturers need dispersants that offer high efficiency and cost-effectiveness.
- RD-99031 (35% Solid): Benchmarked against Tego 760W, this dispersant provides strong versatility and high gloss for inkjet inks and industrial coatings.
- RD-9681 (40% Solid): Benchmarked against Tego 755W, it is highly effective at viscosity reduction and enhancing water and alcohol resistance, which is vital for the longevity of the printed media.
4. Enhanced Substrate Wetting with RK-8212
Achieving the perfect “drop” is only half the battle; the ink must also spread correctly on various substrates, from treated films to non-woven fabrics. The integration of RK-8212 (DC5211) is a powerful solution.
- Super-Wetting: As a silane super-wetting agent, RK-8212 provides fast spreading and high permeability.
- Broad Compatibility: It is suitable for PET film treatment and high-performance water-based coatings, ensuring that Pigment Red 170 adheres flawlessly without shrinkage or pinholes.
5. Superior Compatibility with RD-9208 and RD-9765A
For resin-free pigment pastes or complex hybrid ink systems, the compatibility of the dispersant with downstream resins is paramount.
- RD-9208 (40% Solid): Benchmarked against BYK 190, it is an excellent choice for resin-free color pastes, offering significant viscosity reduction and perfect compatibility with various resins.
- RD-9765A: Benchmarked against BYK 2012, this dispersant ensures that the water-based acrylic or polyurethane resin emulsions used in inkjet bases remain stable and clear.
