What if a single additive could transform your dispersion process?

What if you no longer had to grind multiple pigments individually to achieve optimal color?

For coating formulators, dispersing multiple pigments is often time-intensive and complex, making it a challenge to balance performance, efficiency, and development timelines. Industrial coatings in particular are trending toward one-pot co-grinding of multiple pigments for optimal color and prevention of pigment flocculation. However, dispersants can face several technical challenges in this process, including pigment density differences and surface treatment variability. These challenges can hinder color strength, anti-flooding and anti-floating, and .

Borchi^® Gen 0311 was developed to change that. This APEO-free and tin-free high molecular weight dispersing agent is designed for solventborne polyurethane (PU) co-grinding systems. It enables stronger color development, improved stability, and greater formulation flexibility against competitive co-grinding dispersants across a wide range of pigments.  

A Closer Look at Borchi Gen 0311 Dispersing Agent for PU Coatings

Borchi Gen 0311 is a low viscosity dispersant that supports precise, consistent dosing in both lab and production environments. It appears as a slight yellow liquid with a non-volatile content of 43 to 47 percent and integrates easily into solventborne systems using butyl acetate, xylene, or methoxy propyl acetate. Designed for versatility, it is effective with multiple pigment types, including difficult organic and inorganic pigments and carbon black, where dispersion quality and stability are critical.  

Why Co-Grinding Matters in Pigment Dispersion for Industrial Coatings

Meeting performance targets while staying on schedule is a constant challenge. Grinding pigments individually increases processing time, energy use, and operational complexity. Co-grinding offers a more efficient path by dispersing multiple pigments at once. However, this process can introduce issues such as flocculation, flooding, and floating. Borchi Gen 0311 helps mitigate these risks by stabilizing different pigment types within the same mill base. This allows formulators to streamline production without sacrificing quality.  

Stronger Color Development in Co-Grinding with Advanced Dispersant Technology

Color performance is critical to coating success. Achieving deep, consistent color, especially with organic pigments and carbon black, can be difficult in co-grinding systems. Borchi Gen 0311 delivers stronger color development compared to traditional co-grinding dispersants by effectively separating and stabilizing pigment particles.     The result is richer, more consistent color across complex formulations.  

Improved Dispersion Stability in Multi-Pigment Co-Grinding Systems

Long-term stability is just as important as initial appearance. Co-grinding systems are prone to flooding and floating due to differences in pigment density and surface properties. These issues can impact both performance and visual quality. Borchi Gen 0311 is designed to minimize these effects. Its high molecular weight structure helps maintain separation between pigment particles, reducing the risk of instability over time.   This leads to coatings that retain their color consistency and performance from production through application.  

Broad Pigment Compatibility for Industrial, Automotive, and Marine Coatings

Borchi Gen 0311 is compatible with a wide range of pigment types, making it suitable for diverse industrial applications, including:

• Industrial coatings
• Automotive coatings
• Protective and marine coatings

Improving Efficiency in Co-Grinding for Polyurethane Coating Production

Efficiency is a key advantage of co-grinding. By enabling multiple pigments to be dispersed in a single step, Borchi Gen 0311 helps reduce processing time, energy use, and production complexity.

Stronger color development also supports more efficient use of pigments, helping reduce waste and improve overall formulation performance.  

Simplify Multi-Pigment Dispersions with Borchi Gen 0311 Dispersing Agent

Borchi Gen 0311 gives formulators the ability to simplify dispersion while improving results. With stronger color, improved stability, and broad pigment compatibility, it provides a more reliable approach to co-grinding in solventborne polyurethane systems. If you are looking to streamline your process and achieve better performance, Borchi Gen 0311 is designed to help.
