Understanding Cationic and Nonionic Waterborne Polyurethanes

Meta: Waterborne polyurethane dispersions are commonly categorized by ionic structure, which directly influences their stability, compatibility, and end-use performance. Cationic and nonionic PUDs represent two important classes used in coatings, adhesives, inks, and surface treatment systems. Although both are designed for water-based processing, their internal stabilization mechanisms and substrate interactions differ significantly. These differences guide […]
