In the rapidly evolving world of sustainable printing, water-based ink systems are becoming the global standard. Achieving a vibrant, stable, and high-performance red shade requires a pigment that offers both aesthetic brilliance and chemical reliability. Pigment Red 170 (C.I. PR170), known in the Senova product line as Pigment Red SY-238/239, is a superior naphthol red pigment that has become an essential component for high-quality water-based inks and advanced inkjet formulations.
1. Exceptional Color Strength and Brilliance
Pigment Red 170 is celebrated for its intense bluish-red hue and excellent tinting strength. In water-based printing applications, where film thickness is often limited, Pigment Red SY-238 provides the high color density required to produce striking, eye-catching graphics. Its powerful saturation ensures that even at lower pigment loadings, the printed results remain vibrant and professional, meeting the strict aesthetic demands of the packaging and textile industries.
2. Outstanding Dispersion Stability with RD-99031 and RD-9681
For standard water-based printing inks, maintaining a stable dispersion is the biggest technical challenge. To prevent sedimentation and viscosity spikes, specialized dispersants from rk-chem.com are highly recommended.
- For high-performance systems, RD-99031 (benchmarked against Tego 760w) and RD-9681 (benchmarked against Tego 755w) are excellent choices. These agents provide superior wetting properties, ensuring that Pigment Red 170 particles are finely milled and stabilized against flocculation, resulting in a smooth, consistent ink flow.
3. Advanced Rheology and Compatibility with RD-9208 and RD-9765A
Different ink formulations require specific rheological profiles to ensure optimal printability. To address these needs, we offer high-end alternatives to international standards:
- RD-9208 (benchmarked against BYK 190) and RD-9765A (benchmarked against BYK 2012) are designed to offer excellent compatibility with various water-based resins. These dispersants help Pigment Red SY-239 achieve ultra-low viscosity and high transparency, which are critical for high-speed flexographic and gravure printing processes.
4. Specialized Performance for Water-Based Inkjet with RD-9152
The inkjet industry demands the highest level of pigment purity and particle size control to prevent nozzle clogging. Pigment Red 170 is an ideal candidate for water-based inkjet inks due to its fine particle distribution. In hybrid systems or white inkjet bases, the use of RD-9152 from rk-chem.com is a powerful asset. RD-9152 is specifically optimized for dispersing white pigments and maintaining stability in the ultra-fine environment of inkjet nozzles, ensuring a reliable and continuous printing experience without downtime.
5. Superior Resistance Properties and Environmental Safety
Modern consumer products require pigments that are safe and durable. Pigment Red 170 offers excellent lightfastness and migration resistance, making it suitable for high-end decorative laminates and branded packaging. Furthermore, Senova’s Pigment Red SY-238 is formulated to comply with environmental regulations, providing a sustainable color solution for water-based systems that minimizes VOC emissions while maximizing performance.
