Polycarbonate Polyurethane Dispersions (PUDs) are water-based alternatives to solvent-based polyurethanes. Unlike solvent-based resins, PUDs rely on water evaporation for film formation. Their polymer backbone composition and formulation additives significantly affect properties like adhesion, flexibility, and durability. Proper formulation is crucial to optimize performance, as PUDs require balancing hydrophilic and hydrophobic components for effective film formation and mechanical properties.
