Exploring the benefits of easy-to-disperse pigments in production and performance
In the coatings industry, optimising pigment dispersion is essential for achieving high colour strength, gloss, opacity, and stability. Traditional grinding and dispersion processes require high energy and long processing times, impacting production efficiency and sustainability. The development of easy-to-disperse pigments addresses these challenges by reducing grinding time, energy consumption, and waste generation, while maintaining performance and colour accuracy. By integrating easy-to-disperse pigments, coatings manufacturers can enhance efficiency, reduce energy consumption during the grinding and dispersion process.
Benefits:
The adoption of easy-to-disperse pigment technology delivers significant economic and environmental advantages:
- Reduction in dispersion time: Faster processing, boosting production efficiency and reducing bottlenecks.
- Lower energy consumption: Minimises milling time and equipment usage, reduces operational costs and carbon footprint reduction.
- Enhanced colour strength and stability: Achieves higher tinctorial strength and gloss with minimal processing.
- Improved handling and storage: Free-flowing, low-dusting pigments simplify weighing, dosing, and clean-up, improving workplace safety.
- Regulatory compliance: Biocide-free and eco-label compliant versions available.
Key materials:
To enhance dispersion efficiency, special easy-to-disperse pigment technologies have been developed:
- Dispersed pigment preparations: fully dispersed pigment concentrates available in solid, free-flowing form, eliminating the bead milling step.
- Customer-specific pigment blends: multi-pigment blends are pre-dispersed by dry pre-grinding process, optimised for colour accuracy, processing efficiency, and ensuring good incorporation into formulations.
- Surface-modified organic pigments: pre-treated during manufacturing to enhance wettability and stability, eliminating the need for extensive milling.
