PAT-ADD DA 101

Polyelectrolyte, sodium salt. Acts as a polymeric dispersing agent for inorganic pigments in water. Enables high pigment loading in the mill-base, is non-foaming and contributes to best paint storage stability. Provides excellent retention properties of calcium and metal ions, which attributes to best performance, also in manufacturing conditions using hard water. It is strongly adsorbed onto inorganic pigments and extenders, thus creating a dense charged layer, which contributes to electrostatic stabilization of the dispersed pigment and extender particles. The tendency of pigment flocculation, during paint production, storage or application is reduced, whereas properties like viscosity stability on storage, color development, opacity, scrub-resistance are being optimized. Has high binding capacity for Ca or Mg metal ions. It is specially recommended for use in high PVC dispersion paints.
