High-pigment carbon black and organic pigments are notoriously difficult to disperse—a challenge that is especially common in high-end automotive and industrial coatings. This often leads to increased system viscosity, higher grinding costs, reduced storage stability, and even defects in the dry film such as hue deviation (e.g., reddish carbon black), floating, flooding, and gloss reduction. Our product offers an effective and reliable solution to these issues.
When dealing with high surface area carbon black and structurally complex organic pigments, dispersants often face a dilemma: they must reduce system viscosity while simultaneously maintaining color stability. To meet these demanding requirements, our KBS-6175 dispersing additive features a unique polyurethane copolymer structure and provides a systematic solution. It is analogous to BYK-163 and EFKA-4063. It goes beyond traditional additive functionality by fundamentally restructuring pigment dispersion behavior through a dual stabilization mechanism combining steric hindrance and electrostatic repulsion.
How Does KBS-6175 to Achieve a Balance Between Viscosity Reduction and Color Stability?
1. Steric Hindrance Barrier
Long-chain polymers form a robust three-dimensional protective layer on the pigment surface, acting like a physical scaffold that separates adjacent particles and effectively prevents flocculation and agglomeration caused by Brownian motion.
2. Electrostatic Repulsion
Uniform surface charges are imparted to pigment particles, creating a secondary “safety lock” through electrostatic repulsion. This ensures system stability even under high solid content or high shear conditions.
This “physical + chemical” dual stabilization mechanism effectively resolves the common issue of co-flocculation in multi-component systems, laying a solid foundation for long-term storage stability of coatings.
Why Choose Our KBS-6175?
1. Enhances Blackness Quality
KBS-6175 is specifically designed for high-pigment carbon black. After dispersion, the black paste exhibits a clean, intense bluish undertone, eliminating the common reddish or yellowish hues found in the industry. This ensures precise color matching and high-end coating appearance.
2. Shortens Grinding Time and Production Cycle
KBS-6175 effectively reduces slurry viscosity during grinding, improving efficiency and speed. Under the same energy input, it enables higher output. It also supports high pigment loading formulations, shortening production cycles and delivering direct economic benefits.
3. Improves Gloss, Color Saturation, and Transparency
Only fully dispersed pigments can deliver optimal performance. With KBS-6175, coatings show significant improvements in gloss, color saturation, transparency, and hiding power, resulting in richer and more durable color performance.
4. Broad Application Compatibility
KBS-6175 is highly compatible with two-component polyurethane (2K PU) systems and baking-curing systems. It performs reliably across automotive coatings, industrial anti-corrosion coatings, architectural coatings, and wood coatings, supporting the development of diverse product lines.
Choose our KBS-6175 to effectively solve your coating challenges such as difficult dispersion of high-pigment carbon black, poor stability of organic pigments, and issues like floating and flooding. Feel free to contact us for the TDS and application guidelines.
