Paper Coatings – How Kady International Mills Provide the Optimal Solution

Superior dispersion for high-solids paper coating formulations

In the competitive world of paper manufacturing, the quality of the coating directly determines printability, gloss, smoothness, brightness, and overall value of the final sheet. Achieving a consistent, high-solids coating color with excellent pigment dispersion is critical — and that’s exactly where Kady International rotor-stator mills excel.

Challenges in Paper Coating Production

• High solids content (often 60–75% clay or 65%+ TiO₂)
• Need for extremely fine, uniform particle distribution
• Prevention of agglomeration and settling
• Fast batch turnaround without sacrificing quality
• Energy efficiency and minimal maintenance

How Kady Mills Solve These Challenges

Kady’s high-speed rotor-stator dispersion mills use intense shear, impact, and cavitation forces to rapidly break down pigment agglomerates and create stable, high-quality dispersions in a single step or as an efficient premill.

Key Advantages for Paper Coatings:

• Handles very high solids — easily disperses up to 75% clay solids and 65% TiO₂ solids.
• Exceptional color development — Phthalo Blues and other pigments reach full strength in as little as 45 minutes.
• One-step or PreMilling capability — dramatically reduces or eliminates passes through media mills, saving time and energy.
• Uniform particle size — produces smooth, defect-free coatings with superior gloss and printability.
• Deaeration — helps remove entrained air for better coating application and fewer defects.
