Ultimate Blackness & Solvent-Free Performance | Deep Dive into High-Performance Dispersant RD-9617| Deep Dive into High-Performance Dispersant RD-9617

In today’s high-performance coating industry, achieving the perfect balance between extreme jetness and solvent-free environmental standards is a significant challenge. RD-9617 provides the solution. As a high-molecular-weight polymer dispersant, it combines superior stabilizing power with $99\pm1\%$ active ingredient content, making it the essential additive for solvent-free epoxy and high-solid systems.

1. Performance Showdown: Redefining "Jetness"

Through rigorous drawdown testing, the performance of RD-9617 is clear:

• Left (RD-9617): Exhibits a deep, rich, and "piano-black" finish. RD-9617 successfully de-agglomerates carbon black particles and provides long-term stability through steric hindrance, ensuring maximum color development.

• Center (Leading German Competitor): While functional, the blackness is noticeably shallower, showing a "grayish" undertone caused by incomplete dispersion.

• Right (No Additives): Significant flocculation occurs, resulting in a dull, matte, and grainy surface.

2. Core Technical Advantages

• 
  

  100% Active Content for Eco-Friendly Systems: Unlike many dispersants on the market, RD-9617 has an active content of nearly 100%. This allows for maximum formulation flexibility in solvent-free epoxy systems, UV wood coatings, and high-solid industrial paints without introducing unwanted VOCs.

  
  

• Exceptional Viscosity Reduction: Carbon black, especially high-surface-area types, tends to drastically increase system viscosity. RD-9617 offers an excellent viscosity reduction effect, maintaining flowability even in high-powder-loading systems and optimizing production efficiency.

  
  

• 
  

  Broad System Compatibility: Specifically designed for solvent-based coatings and ink systems. It performs reliably across plastic, wood, floor, and coil coatings.

4. Application & Dosage Guidelines

To achieve optimal performance, we recommend the following application method:

• 
  

  Usage: First, dissolve RD-9617 completely into the grinding resin/base material mixture, then add the pigments for the grinding process.

• 
  

  Recommended Dosage (Based on Pigment Weight):

• High Surface Carbon Black: 40-80%

• Low Surface Carbon Black: 10-20%

• Organic Pigments: 7-15%

Conclusion

RD-9617 is our professional answer to the most difficult carbon black dispersion challenges. It not only delivers extreme color performance but also helps your formulations transition toward a more efficient and environmentally friendly future.
